phenotypic.grid package

Grid discovery for plated fungal colonies.

Provides tools to define the row/column layout of arrayed plates (e.g., 96- or 384-spot) so downstream detection and measurements align colonies to expected wells. Supports automatic grid inference and manual specification for challenging imaging conditions.

args

class phenotypic.grid.AutoGridFinder(*, nrows: Annotated[int, TuneSpec(low=None, high=None, step=None, log=False, categories=None, tunable=False)] = 8, ncols: Annotated[int, TuneSpec(low=None, high=None, step=None, log=False, categories=None, tunable=False)] = 12, residual_fraction: Annotated[float, TuneSpec(low=0.1, high=0.5, step=None, log=False, categories=None, tunable=True)] = 0.25, warn: bool = False, tol: Annotated[float | None, TuneSpec(low=None, high=None, step=None, log=False, categories=None, tunable=False)] = None, max_iter: Annotated[int | None, TuneSpec(low=None, high=None, step=None, log=False, categories=None, tunable=False)] = None)

Bases: GridFinder

Automatically determines grid row and column edges from detected object centers using a deterministic robust-fit algorithm.

Unlike histogram or optimizer-based approaches, this class fits a regular grid model directly to the per-object distance-transform maximum centers (deepest interior point of each object’s mask). These centers are anchored in the dense colony body and are unaffected by thin filamentous extensions (e.g., fungal hyphae) that would otherwise pull intensity-weighted centroids off-body and bias the grid fit. Outlier rejection further protects against atypical objects pulling boundaries away from the true positions.

Args:

nrows: Number of rows in the grid (default 8 for 96-well plates). ncols: Number of columns in the grid (default 12 for 96-well plates). residual_fraction: Outlier threshold as a fraction of pitch. Centers

whose fit residual exceeds pitch * residual_fraction are excluded from the refined fit (default 0.25).

warn: Whether to emit AutoGridFinderFallbackWarning

diagnostics for fallbacks, geometry overrides, and span-coverage anchoring decisions. Defaults to False (silent); set to True to surface them.

tol: Deprecated. Accepted for backward compatibility but ignored. max_iter: Deprecated. Accepted for backward compatibility but ignored.

Notes:

Span-coverage handling: when the detected span of occupied grid indices is less than n_expected by more than _SPAN_TOLERANCE (default 1 — a single entirely-empty edge row/column is silently tolerated), the fitter compares the leftmost and rightmost centroids to the fit’s predicted cell-0 and cell-(n-1) centers. When one end aligns within pitch / 2 of its predicted boundary cell, that side is treated as the anchored edge and the fitted offset is preserved (no override). The three diagnostic tags [span-coverage-low] / [span-coverage-high] / [span-coverage-symmetric] document which decision was made; warn=True surfaces them. To loosen or tighten the tolerance, subclass and override _SPAN_TOLERANCE.

Diagnostic warnings of category AutoGridFinderFallbackWarning are emitted at every fallback (uniform spacing, simple-pipeline switch, span-based pitch), geometry override (pitch shrink), and span-coverage anchor decision. Suppress them in batch runs with:

import warnings
from phenotypic.grid._auto_grid_finder import (
    AutoGridFinderFallbackWarning,
)
warnings.filterwarnings(
    "ignore", category=AutoGridFinderFallbackWarning,
)

Category: Grid

Name	Description
RowNum	The row idx of the object
RowIntervalStart	The start of the row interval of the object
RowIntervalEnd	The end of the row interval of the object
ColNum	The column idx of the object
ColIntervalStart	The start of the column interval of the object
ColIntervalEnd	The end of the column interval of the object
RowMajorIdx	The row-major index of the object. Row major is the standard in most programming and data science array libraries. Used for indexing into 2D arrays.
ColMajorIdx	The col-major index of the object in an array. Lab automation logic uses column-major (column-wise) indexing for well plate operations because 96-well plates are physically arranged with 8 rows (labeled A-H) and 12 columns (numbered 1-12), and this layout maps directly to how multichannel pipettes operate.

Parameters:

• nrows (Annotated[int, TuneSpec(low=None, high=None, step=None, log=False, categories=None, tunable=False)])

• ncols (Annotated[int, TuneSpec(low=None, high=None, step=None, log=False, categories=None, tunable=False)])

• residual_fraction (Annotated[float, TuneSpec(low=0.1, high=0.5, step=None, log=False, categories=None, tunable=True)])

• warn (bool)

• tol (Annotated[float | None, TuneSpec(low=None, high=None, step=None, log=False, categories=None, tunable=False)])

• max_iter (Annotated[int | None, TuneSpec(low=None, high=None, step=None, log=False, categories=None, tunable=False)])

classmethod __get_pydantic_json_schema__(core_schema: CoreSchema, handler: GetJsonSchemaHandler, /) → JsonSchemaValue

Hook into generating the model’s JSON schema.

Parameters:

• core_schema (CoreSchema) – A pydantic-core CoreSchema. You can ignore this argument and call the handler with a new CoreSchema, wrap this CoreSchema ({‘type’: ‘nullable’, ‘schema’: current_schema}), or just call the handler with the original schema.

• handler (GetJsonSchemaHandler) – Call into Pydantic’s internal JSON schema generation. This will raise a pydantic.errors.PydanticInvalidForJsonSchema if JSON schema generation fails. Since this gets called by BaseModel.model_json_schema you can override the schema_generator argument to that function to change JSON schema generation globally for a type.

Returns:

A JSON schema, as a Python object.

Return type:

JsonSchemaValue

classmethod __pydantic_init_subclass__(**kwargs: Any) → None

Populate field descriptions from the subclass docstring.

Runs once per concrete subclass after pydantic has built its model. Copies parameter descriptions parsed from the Google-style Args: docstring block onto each field’s description slot so they surface in model_json_schema() — the machine-readable contract used by downstream tooling (e.g. an MCP server).

Parameters:

**kwargs (Any) – Class-keyword arguments forwarded by pydantic.

Return type:

None

classmethod __pydantic_on_complete__() → None

This is called once the class and its fields are fully initialized and ready to be used.

This typically happens when the class is created (just before [__pydantic_init_subclass__()][pydantic.main.BaseModel.__pydantic_init_subclass__] is called on the superclass), except when forward annotations are used that could not immediately be resolved. In that case, it will be called later, when the model is rebuilt automatically or explicitly using [model_rebuild()][pydantic.main.BaseModel.model_rebuild].

Return type:

None

classmethod construct(_fields_set: set[str] | None = None, **values: Any) → Self

Parameters:

• _fields_set (set[str] | None)

• values (Any)

Return type:

Self

classmethod from_json(json_data: str | Path | dict) → BaseOperation

Reconstruct an operation from JSON written by to_json().

Accepts a JSON string, a path to a JSON file, or a pre-parsed envelope dict (same input handling as ImagePipeline.from_json()). Polymorphic: ImageOperation.from_json(path) returns whatever concrete operation the file holds. When called on a narrower subclass, the resolved class must be a subclass of it, else a TypeError is raised.

Parameters:

json_data (str | Path | dict) – A JSON string, path to a JSON file, or envelope dict.

Returns:

The reconstructed operation instance.

Raises:

• AttributeError – If the recorded class cannot be resolved in the phenotypic namespace.

• TypeError – If called on a concrete subclass and the file holds a class that is not a subclass of it.

Return type:

BaseOperation

Example

>>> import tempfile
>>> from pathlib import Path
>>> from phenotypic.abc_ import ImageOperation
>>> from phenotypic.detect import OtsuDetector
>>> with tempfile.TemporaryDirectory() as d:
...     p = Path(d) / "op.json"
...     OtsuDetector().to_json(p)
...     loaded = ImageOperation.from_json(p)  # polymorphic
>>> type(loaded).__name__
'OtsuDetector'

classmethod from_orm(obj: Any) → Self

Parameters:

obj (Any)

Return type:

Self

classmethod model_construct(_fields_set: set[str] | None = None, **values: Any) → Self

Creates a new instance of the Model class with validated data.

Creates a new model setting __dict__ and __pydantic_fields_set__ from trusted or pre-validated data. Default values are respected, but no other validation is performed.

!!! note

model_construct() generally respects the model_config.extra setting on the provided model. That is, if model_config.extra == ‘allow’, then all extra passed values are added to the model instance’s __dict__ and __pydantic_extra__ fields. If model_config.extra == ‘ignore’ (the default), then all extra passed values are ignored. Because no validation is performed with a call to model_construct(), having model_config.extra == ‘forbid’ does not result in an error if extra values are passed, but they will be ignored.

Parameters:

• _fields_set (set[str] | None) – A set of field names that were originally explicitly set during instantiation. If provided, this is directly used for the [model_fields_set][pydantic.BaseModel.model_fields_set] attribute. Otherwise, the field names from the values argument will be used.

• values (Any) – Trusted or pre-validated data dictionary.

Returns:

A new instance of the Model class with validated data.

Return type:

Self

classmethod model_json_schema(by_alias: bool = True, ref_template: str = '#/$defs/{model}', schema_generator: type[~pydantic.json_schema.GenerateJsonSchema] = <class 'pydantic.json_schema.GenerateJsonSchema'>, mode: ~typing.Literal['validation', 'serialization'] = 'validation', *, union_format: ~typing.Literal['any_of', 'primitive_type_array'] = 'any_of') → dict[str, Any]

Generates a JSON schema for a model class.

Parameters:

• by_alias (bool) – Whether to use attribute aliases or not.

• ref_template (str) – The reference template.

• union_format (Literal['any_of', 'primitive_type_array']) –

  The format to use when combining schemas from unions together. Can be one of:

  • ’any_of’: Use the [anyOf](https://json-schema.org/understanding-json-schema/reference/combining#anyOf)

  keyword to combine schemas (the default). - ‘primitive_type_array’: Use the [type](https://json-schema.org/understanding-json-schema/reference/type) keyword as an array of strings, containing each type of the combination. If any of the schemas is not a primitive type (string, boolean, null, integer or number) or contains constraints/metadata, falls back to any_of.

• schema_generator (type[GenerateJsonSchema]) – To override the logic used to generate the JSON schema, as a subclass of GenerateJsonSchema with your desired modifications

• mode (Literal['validation', 'serialization']) – The mode in which to generate the schema.

Returns:

The JSON schema for the given model class.

Return type:

dict[str, Any]

classmethod model_parametrized_name(params: tuple[type[Any], ...]) → str

Returns:

String representing the new class where params are passed to cls as type variables.

Raises:

TypeError – Raised when trying to generate concrete names for non-generic models.

Return type:

str

copy(*, include: AbstractSetIntStr | MappingIntStrAny | None = None, exclude: AbstractSetIntStr | MappingIntStrAny | None = None, update: Dict[str, Any] | None = None, deep: bool = False) → Self

Returns a copy of the model.

!!! warning “Deprecated”

This method is now deprecated; use model_copy instead.

If you need include or exclude, use:

`python {test="skip" lint="skip"} data = self.model_dump(include=include, exclude=exclude, round_trip=True) data = {**data, **(update or {})} copied = self.model_validate(data) `

Parameters:

• include (AbstractSetIntStr | MappingIntStrAny | None) – Optional set or mapping specifying which fields to include in the copied model.

• exclude (AbstractSetIntStr | MappingIntStrAny | None) – Optional set or mapping specifying which fields to exclude in the copied model.

• update (Dict[str, Any] | None) – Optional dictionary of field-value pairs to override field values in the copied model.

• deep (bool) – If True, the values of fields that are Pydantic models will be deep-copied.

dashboard(image: Image, show_progress: bool = True) → Any

Notebook Plotly diagnostic dashboard for grid fitting.

Profiles the grid-fitting pipeline and returns a single composed plotly.graph_objects.Figure stacking the timing breakdown, object-size distribution, centroid scatter with grid overlay, per-axis spacing and occupancy panels, and a summary table. Useful for identifying bottlenecks when grid.info() is slow (e.g. with filamentous fungi images).

The figures are built by the transient GridFitReport provider; because every panel is control-free, report.dash() composes them into one vertical subplot figure. Uses an ipywidgets progress bar in Jupyter, tqdm otherwise.

Parameters:

• image (Image) – Image with detected objects (must have objmap).

• show_progress (bool) – Whether to display a progress bar during profiling. Defaults to True.

Returns:

A composed plotly.graph_objects.Figure with all diagnostic panels stacked vertically.

Return type:

Any

Notes

The inspect() name is reserved across the codebase for methods returning a saveable figure consumed by the CLI’s --save-inspect flag. This diagnostic surface is exposed under dashboard() instead, and AutoGridFinder does not mix in FigureProvider so no inspect() is auto-discovered.

Examples

>>> from phenotypic.data import load_synth_yeast_plate
>>> from phenotypic.detect import OtsuDetector
>>> from phenotypic.grid import AutoGridFinder
>>> image = load_synth_yeast_plate()
>>> image = OtsuDetector().apply(image)
>>> finder = AutoGridFinder(nrows=8, ncols=12)
>>> dashboard = finder.dashboard(image)

model_copy(*, update: Mapping[str, Any] | None = None, deep: bool = False) → Self

!!! abstract “Usage Documentation”

[model_copy](../concepts/models.md#model-copy)

Returns a copy of the model.

!!! note

The underlying instance’s [__dict__][object.__dict__] attribute is copied. This might have unexpected side effects if you store anything in it, on top of the model fields (e.g. the value of [cached properties][functools.cached_property]).

Parameters:

• update (Mapping[str, Any] | None) – Values to change/add in the new model. Note: the data is not validated before creating the new model. You should trust this data.

• deep (bool) – Set to True to make a deep copy of the model.

[model_dump](../concepts/serialization.md#python-mode)

Generate a dictionary representation of the model, optionally specifying which fields to include or exclude.

Parameters:

• mode (Literal['json', 'python'] | str) – The mode in which to_python should run. If mode is ‘json’, the output will only contain JSON serializable types. If mode is ‘python’, the output may contain non-JSON-serializable Python objects.

• include (set[int] | set[str] | Mapping[int, set[int] | set[str] | Mapping[int, IncEx | bool] | Mapping[str, IncEx | bool] | bool] | Mapping[str, set[int] | set[str] | Mapping[int, IncEx | bool] | Mapping[str, IncEx | bool] | bool] | None) – A set of fields to include in the output.

• exclude (set[int] | set[str] | Mapping[int, set[int] | set[str] | Mapping[int, IncEx | bool] | Mapping[str, IncEx | bool] | bool] | Mapping[str, set[int] | set[str] | Mapping[int, IncEx | bool] | Mapping[str, IncEx | bool] | bool] | None) – A set of fields to exclude from the output.

• context (Any | None) – Additional context to pass to the serializer.

• by_alias (bool | None) – Whether to use the field’s alias in the dictionary key if defined.

• exclude_unset (bool) – Whether to exclude fields that have not been explicitly set.

• exclude_defaults (bool) – Whether to exclude fields that are set to their default value.

model_post_init(_AutoGridFinder__context: Any) → None

Warn on deprecated tol / max_iter parameters.

Reproduces the legacy __init__ deprecation warnings, then delegates to BaseOperation.model_post_init() for logger and memory-tracking setup.

Parameters:

• __context – Pydantic post-init context (unused).

• _AutoGridFinder__context (Any)

Return type:

None

to_json(filepath: str | Path | None = None) → str | None

Serialize this operation to JSON.

Captures the operation as a {"class", "params"} envelope: params is model_dump(mode="json") (every declared field, including nested operations and raw arrays; PrivateAttr state such as loggers and timing is excluded automatically), and class records the concrete class name so from_json() can rebuild the right subclass. This mirrors ImagePipeline.to_json().

Parameters:

filepath (str | Path | None) – Optional path to write the JSON to. When None, the JSON string is returned instead. Accepts a str or Path.

Returns:

The JSON string when filepath is None, otherwise None.

Return type:

str | None

Example

>>> import tempfile
>>> from pathlib import Path
>>> from phenotypic.detect import OtsuDetector
>>> from phenotypic.sdk_ import CONFIG_SUFFIX_OPERATION, ensure_typed_json_suffix
>>> with tempfile.TemporaryDirectory() as d:

...     saved = ensure_typed_json_suffix(p, CONFIG_SUFFIX_OPERATION)
...     OtsuDetector(ignore_zeros=True).to_json(p)

Returns:

A set of strings representing the fields that have been set,

i.e. that were not filled from defaults.

ncols: Annotated[int, TuneSpec(tunable=False)]

nrows: Annotated[int, TuneSpec(tunable=False)]

Bases: GridFinder

Center-anchored grid finder for sparse arrayed plates.

Fits a regular axis-aligned grid (single isotropic pitch + center) to detected colony centers by their periodicity rather than their span, so it survives empty edge/interior rows that break span-based fitting. Assumes the plate is roughly centered in the (de-rotated) frame. See the design spec for the algorithm.

Parameters:

• nrows (Annotated[int, TuneSpec(low=None, high=None, step=None, log=False, categories=None, tunable=False)]) – Number of grid rows (default 8 — 96-well plate).

• ncols (Annotated[int, TuneSpec(low=None, high=None, step=None, log=False, categories=None, tunable=False)]) – Number of grid columns (default 12 — 96-well plate).

• residual_fraction (Annotated[float, TuneSpec(low=0.1, high=0.5, step=None, log=False, categories=None, tunable=True)]) – ICP robust-trim threshold as a fraction of pitch (default 0.25).

• n_pitch_samples (Annotated[int, TuneSpec(low=None, high=None, step=None, log=False, categories=None, tunable=False)]) – Comb-response scan resolution (default 512).

• response_floor (Annotated[float, TuneSpec(low=0.5, high=0.95, step=None, log=False, categories=None, tunable=True)]) – Fundamental-selection threshold as a fraction of the peak comb-response (default 0.8).

• max_iter (Annotated[int, TuneSpec(low=None, high=None, step=None, log=False, categories=None, tunable=False)]) – ICP iteration cap per multi-start candidate (default 6).

• min_fit_objects (Annotated[int, TuneSpec(low=None, high=None, step=None, log=False, categories=None, tunable=False)]) – Below this colony count the fit is treated as bounded-ambiguous (default 6).

• warn (bool) – Emit CenteredAutoGridFinderFallbackWarning (default False).

Notes

nrows/ncols must match the physical plate; a mismatch produces a wrong grid silently (no internal guard). For multiple colonies per well use a downstream refiner (KeepNearestCenter / KeepSectionLargest / MergeWithinSection); this finder assigns faithfully, many-to-one.

Examples

Default 96-well fit on the bundled synthetic plate:

>>> from phenotypic.data import load_synth_yeast_plate
>>> from phenotypic.detect import OtsuDetector
>>> from phenotypic.grid import CenteredAutoGridFinder
>>> image = OtsuDetector().apply(load_synth_yeast_plate())
>>> finder = CenteredAutoGridFinder(nrows=8, ncols=12)
>>> grid_df = finder.measure(image)
>>> len(finder.get_row_edges(image)) == 9
True
>>> len(finder.get_col_edges(image)) == 13
True

classmethod __get_pydantic_json_schema__(core_schema: CoreSchema, handler: GetJsonSchemaHandler, /) → JsonSchemaValue

Hook into generating the model’s JSON schema.

Parameters:

• core_schema (CoreSchema) – A pydantic-core CoreSchema. You can ignore this argument and call the handler with a new CoreSchema, wrap this CoreSchema ({‘type’: ‘nullable’, ‘schema’: current_schema}), or just call the handler with the original schema.

• handler (GetJsonSchemaHandler) – Call into Pydantic’s internal JSON schema generation. This will raise a pydantic.errors.PydanticInvalidForJsonSchema if JSON schema generation fails. Since this gets called by BaseModel.model_json_schema you can override the schema_generator argument to that function to change JSON schema generation globally for a type.

Returns:

A JSON schema, as a Python object.

Return type:

JsonSchemaValue

classmethod __pydantic_init_subclass__(**kwargs: Any) → None

Populate field descriptions from the subclass docstring.

Runs once per concrete subclass after pydantic has built its model. Copies parameter descriptions parsed from the Google-style Args: docstring block onto each field’s description slot so they surface in model_json_schema() — the machine-readable contract used by downstream tooling (e.g. an MCP server).

Parameters:

**kwargs (Any) – Class-keyword arguments forwarded by pydantic.

Return type:

None

classmethod __pydantic_on_complete__() → None

This is called once the class and its fields are fully initialized and ready to be used.

This typically happens when the class is created (just before [__pydantic_init_subclass__()][pydantic.main.BaseModel.__pydantic_init_subclass__] is called on the superclass), except when forward annotations are used that could not immediately be resolved. In that case, it will be called later, when the model is rebuilt automatically or explicitly using [model_rebuild()][pydantic.main.BaseModel.model_rebuild].

Return type:

None

classmethod construct(_fields_set: set[str] | None = None, **values: Any) → Self

Parameters:

• _fields_set (set[str] | None)

• values (Any)

Return type:

Self

classmethod from_json(json_data: str | Path | dict) → BaseOperation

Reconstruct an operation from JSON written by to_json().

Accepts a JSON string, a path to a JSON file, or a pre-parsed envelope dict (same input handling as ImagePipeline.from_json()). Polymorphic: ImageOperation.from_json(path) returns whatever concrete operation the file holds. When called on a narrower subclass, the resolved class must be a subclass of it, else a TypeError is raised.

Parameters:

json_data (str | Path | dict) – A JSON string, path to a JSON file, or envelope dict.

Returns:

The reconstructed operation instance.

Raises:

• AttributeError – If the recorded class cannot be resolved in the phenotypic namespace.

• TypeError – If called on a concrete subclass and the file holds a class that is not a subclass of it.

Return type:

BaseOperation

Example

>>> import tempfile
>>> from pathlib import Path
>>> from phenotypic.abc_ import ImageOperation
>>> from phenotypic.detect import OtsuDetector
>>> with tempfile.TemporaryDirectory() as d:
...     p = Path(d) / "op.json"
...     OtsuDetector().to_json(p)
...     loaded = ImageOperation.from_json(p)  # polymorphic
>>> type(loaded).__name__
'OtsuDetector'

classmethod from_orm(obj: Any) → Self

Parameters:

obj (Any)

Return type:

classmethod model_construct(_fields_set: set[str] | None = None, **values: Any) → Self

Creates a new instance of the Model class with validated data.

Creates a new model setting __dict__ and __pydantic_fields_set__ from trusted or pre-validated data. Default values are respected, but no other validation is performed.

!!! note

model_construct() generally respects the model_config.extra setting on the provided model. That is, if model_config.extra == ‘allow’, then all extra passed values are added to the model instance’s __dict__ and __pydantic_extra__ fields. If model_config.extra == ‘ignore’ (the default), then all extra passed values are ignored. Because no validation is performed with a call to model_construct(), having model_config.extra == ‘forbid’ does not result in an error if extra values are passed, but they will be ignored.

Parameters:

• _fields_set (set[str] | None) – A set of field names that were originally explicitly set during instantiation. If provided, this is directly used for the [model_fields_set][pydantic.BaseModel.model_fields_set] attribute. Otherwise, the field names from the values argument will be used.

• values (Any) – Trusted or pre-validated data dictionary.

Returns:

A new instance of the Model class with validated data.

Return type:

Self

classmethod model_json_schema(by_alias: bool = True, ref_template: str = '#/$defs/{model}', schema_generator: type[~pydantic.json_schema.GenerateJsonSchema] = <class 'pydantic.json_schema.GenerateJsonSchema'>, mode: ~typing.Literal['validation', 'serialization'] = 'validation', *, union_format: ~typing.Literal['any_of', 'primitive_type_array'] = 'any_of') → dict[str, Any]

Generates a JSON schema for a model class.

Parameters:

• by_alias (bool) – Whether to use attribute aliases or not.

• ref_template (str) – The reference template.

• union_format (Literal['any_of', 'primitive_type_array']) –

  The format to use when combining schemas from unions together. Can be one of:

  • ’any_of’: Use the [anyOf](https://json-schema.org/understanding-json-schema/reference/combining#anyOf)

  keyword to combine schemas (the default). - ‘primitive_type_array’: Use the [type](https://json-schema.org/understanding-json-schema/reference/type) keyword as an array of strings, containing each type of the combination. If any of the schemas is not a primitive type (string, boolean, null, integer or number) or contains constraints/metadata, falls back to any_of.

• schema_generator (type[GenerateJsonSchema]) – To override the logic used to generate the JSON schema, as a subclass of GenerateJsonSchema with your desired modifications

• mode (Literal['validation', 'serialization']) – The mode in which to generate the schema.

Returns:

The JSON schema for the given model class.

Return type:

dict[str, Any]

classmethod model_parametrized_name(params: tuple[type[Any], ...]) → str

Returns:

String representing the new class where params are passed to cls as type variables.

Raises:

TypeError – Raised when trying to generate concrete names for non-generic models.

Return type:

str

model_copy(*, update: Mapping[str, Any] | None = None, deep: bool = False) → Self

!!! abstract “Usage Documentation”

[model_copy](../concepts/models.md#model-copy)

Returns a copy of the model.

!!! note

The underlying instance’s [__dict__][object.__dict__] attribute is copied. This might have unexpected side effects if you store anything in it, on top of the model fields (e.g. the value of [cached properties][functools.cached_property]).

Parameters:

• update (Mapping[str, Any] | None) – Values to change/add in the new model. Note: the data is not validated before creating the new model. You should trust this data.

• deep (bool) – Set to True to make a deep copy of the model.

[model_dump](../concepts/serialization.md#python-mode)

Generate a dictionary representation of the model, optionally specifying which fields to include or exclude.

Parameters:

• mode (Literal['json', 'python'] | str) – The mode in which to_python should run. If mode is ‘json’, the output will only contain JSON serializable types. If mode is ‘python’, the output may contain non-JSON-serializable Python objects.

!!! abstract “Usage Documentation”

[model_dump_json](../concepts/serialization.md#json-mode)

Generates a JSON representation of the model using Pydantic’s to_json method.

Parameters:

Returns:

A JSON string representation of the model.

Return type:

str

model_post_init(_BaseOperation__context: Any) → None

Initialize logging and memory tracking after model construction.

Replaces the legacy __init__ body: creates the per-class logger and, when that logger is enabled for INFO level or higher, starts tracemalloc so per-operation memory usage can be logged.

Parameters:

• __context – Pydantic post-init context (unused).

• _BaseOperation__context (Any)

Return type:

None

to_json(filepath: str | Path | None = None) → str | None

Serialize this operation to JSON.

Captures the operation as a {"class", "params"} envelope: params is model_dump(mode="json") (every declared field, including nested operations and raw arrays; PrivateAttr state such as loggers and timing is excluded automatically), and class records the concrete class name so from_json() can rebuild the right subclass. This mirrors ImagePipeline.to_json().

Parameters:

filepath (str | Path | None) – Optional path to write the JSON to. When None, the JSON string is returned instead. Accepts a str or Path.

Returns:

The JSON string when filepath is None, otherwise None.

Return type:

str | None

Example

>>> import tempfile
>>> from pathlib import Path
>>> from phenotypic.detect import OtsuDetector
>>> from phenotypic.sdk_ import CONFIG_SUFFIX_OPERATION, ensure_typed_json_suffix
>>> with tempfile.TemporaryDirectory() as d:
...     p = Path(d) / "op.json"

Bases: GridCorrector

Apply a PhenoTypic operation to each grid section of a plate image.

GridApply slices a GridImage into its individual grid sections (wells), applies the wrapped operation to each section in isolation, and writes the transformed sections back into the parent image. It is the building block prefab pipelines use to run a per-well detection or enhancement sub-pipeline.

Parameters:

• image_op (Annotated[Any, BeforeValidator(func=~phenotypic.sdk_.typing_._deserialize_operation_value, json_schema_input_type=PydanticUndefined), AfterValidator(func=~phenotypic.sdk_.typing_._make_require_value.<locals>._require), PlainSerializer(func=~phenotypic.sdk_.typing_._serialize_operation_value, return_type=PydanticUndefined, when_used=always), _OperationFieldMarker()]) – The operation (or nested ImagePipeline) applied to every grid section. Serialized as a class-tagged payload so the concrete operation type round-trips through JSON.

• reset_enh_matrix (bool) – Whether to reset the detect_mat attribute of each section before applying image_op. Defaults to True.

Returns:

The input image with every grid section transformed by image_op.

Return type:

GridImage

classmethod __get_pydantic_json_schema__(core_schema: CoreSchema, handler: GetJsonSchemaHandler, /) → JsonSchemaValue

Hook into generating the model’s JSON schema.

Parameters:

• core_schema (CoreSchema) – A pydantic-core CoreSchema. You can ignore this argument and call the handler with a new CoreSchema, wrap this CoreSchema ({‘type’: ‘nullable’, ‘schema’: current_schema}), or just call the handler with the original schema.

• handler (GetJsonSchemaHandler) – Call into Pydantic’s internal JSON schema generation. This will raise a pydantic.errors.PydanticInvalidForJsonSchema if JSON schema generation fails. Since this gets called by BaseModel.model_json_schema you can override the schema_generator argument to that function to change JSON schema generation globally for a type.

Returns:

A JSON schema, as a Python object.

Return type:

JsonSchemaValue

classmethod __pydantic_init_subclass__(**kwargs: Any) → None

Populate field descriptions from the subclass docstring.

Runs once per concrete subclass after pydantic has built its model. Copies parameter descriptions parsed from the Google-style Args: docstring block onto each field’s description slot so they surface in model_json_schema() — the machine-readable contract used by downstream tooling (e.g. an MCP server).

Parameters:

**kwargs (Any) – Class-keyword arguments forwarded by pydantic.

Return type:

None

classmethod __pydantic_on_complete__() → None

This is called once the class and its fields are fully initialized and ready to be used.

This typically happens when the class is created (just before [__pydantic_init_subclass__()][pydantic.main.BaseModel.__pydantic_init_subclass__] is called on the superclass), except when forward annotations are used that could not immediately be resolved. In that case, it will be called later, when the model is rebuilt automatically or explicitly using [model_rebuild()][pydantic.main.BaseModel.model_rebuild].

Return type:

None

classmethod construct(_fields_set: set[str] | None = None, **values: Any) → Self

Parameters:

• _fields_set (set[str] | None)

• values (Any)

Return type:

Self

classmethod from_json(json_data: str | Path | dict) → BaseOperation

Reconstruct an operation from JSON written by to_json().

Accepts a JSON string, a path to a JSON file, or a pre-parsed envelope dict (same input handling as ImagePipeline.from_json()). Polymorphic: ImageOperation.from_json(path) returns whatever concrete operation the file holds. When called on a narrower subclass, the resolved class must be a subclass of it, else a TypeError is raised.

Parameters:

json_data (str | Path | dict) – A JSON string, path to a JSON file, or envelope dict.

Returns:

The reconstructed operation instance.

Raises:

• AttributeError – If the recorded class cannot be resolved in the phenotypic namespace.

• TypeError – If called on a concrete subclass and the file holds a class that is not a subclass of it.

Return type:

BaseOperation

Example

>>> import tempfile
>>> from pathlib import Path
>>> from phenotypic.abc_ import ImageOperation
>>> from phenotypic.detect import OtsuDetector
>>> with tempfile.TemporaryDirectory() as d:
...     p = Path(d) / "op.json"
...     OtsuDetector().to_json(p)
...     loaded = ImageOperation.from_json(p)  # polymorphic
>>> type(loaded).__name__
'OtsuDetector'

classmethod from_orm(obj: Any) → Self

Parameters:

obj (Any)

Return type:

Self

classmethod model_construct(_fields_set: set[str] | None = None, **values: Any) → Self

Creates a new instance of the Model class with validated data.

Creates a new model setting __dict__ and __pydantic_fields_set__ from trusted or pre-validated data. Default values are respected, but no other validation is performed.

!!! note

model_construct() generally respects the model_config.extra setting on the provided model. That is, if model_config.extra == ‘allow’, then all extra passed values are added to the model instance’s __dict__ and __pydantic_extra__ fields. If model_config.extra == ‘ignore’ (the default), then all extra passed values are ignored. Because no validation is performed with a call to model_construct(), having model_config.extra == ‘forbid’ does not result in an error if extra values are passed, but they will be ignored.

Parameters:

• _fields_set (set[str] | None) – A set of field names that were originally explicitly set during instantiation. If provided, this is directly used for the [model_fields_set][pydantic.BaseModel.model_fields_set] attribute. Otherwise, the field names from the values argument will be used.

• values (Any) – Trusted or pre-validated data dictionary.

Returns:

A new instance of the Model class with validated data.

Return type:

Self

classmethod model_json_schema(by_alias: bool = True, ref_template: str = '#/$defs/{model}', schema_generator: type[~pydantic.json_schema.GenerateJsonSchema] = <class 'pydantic.json_schema.GenerateJsonSchema'>, mode: ~typing.Literal['validation', 'serialization'] = 'validation', *, union_format: ~typing.Literal['any_of', 'primitive_type_array'] = 'any_of') → dict[str, Any]

Generates a JSON schema for a model class.

Parameters:

• by_alias (bool) – Whether to use attribute aliases or not.

• ref_template (str) – The reference template.

• union_format (Literal['any_of', 'primitive_type_array']) –

  The format to use when combining schemas from unions together. Can be one of:

  • ’any_of’: Use the [anyOf](https://json-schema.org/understanding-json-schema/reference/combining#anyOf)

  keyword to combine schemas (the default). - ‘primitive_type_array’: Use the [type](https://json-schema.org/understanding-json-schema/reference/type) keyword as an array of strings, containing each type of the combination. If any of the schemas is not a primitive type (string, boolean, null, integer or number) or contains constraints/metadata, falls back to any_of.

• schema_generator (type[GenerateJsonSchema]) – To override the logic used to generate the JSON schema, as a subclass of GenerateJsonSchema with your desired modifications

• mode (Literal['validation', 'serialization']) – The mode in which to generate the schema.

Returns:

The JSON schema for the given model class.

Return type:

dict[str, Any]

classmethod model_parametrized_name(params: tuple[type[Any], ...]) → str

Compute the class name for parametrizations of generic classes.

This method can be overridden to achieve a custom naming scheme for generic BaseModels.

Parameters:

Returns:

String representing the new class where params are passed to cls as type variables.

Raises:

TypeError – Raised when trying to generate concrete names for non-generic models.

Return type:

str

Return type:

Self

__del__()

Automatically stop tracemalloc when the object is deleted.

__init__(**data: Any) → None

Create a new model by parsing and validating input data from keyword arguments.

Raises [ValidationError][pydantic_core.ValidationError] if the input data cannot be validated to form a valid model.

self is explicitly positional-only to allow self as a field name.

Parameters:

data (Any)

Return type:

None

__iter__() → Generator[tuple[str, Any], None, None]

So dict(model) works.

Return type:

Generator[tuple[str, Any], None, None]

__pretty__(fmt: Callable[[Any], Any], **kwargs: Any) → Generator[Any]

Used by devtools (https://python-devtools.helpmanual.io/) to pretty print objects.

Parameters:

• fmt (Callable[[Any], Any])

• kwargs (Any)

Return type:

Generator[Any]

__repr_name__() → str

Name of the instance’s class, used in __repr__.

Return type:

str

__repr_recursion__(object: Any) → str

Returns the string representation of a recursive object.

Parameters:

object (Any)

Return type:

RichReprResult

apply(image: GridImage, inplace=False) → GridImage

Calculates the optimal rotation angle and applies it to a grid image for alignment along the specified axis.

The method performs alignment of a GridImage object along either nrows or columns based on the specified axis. It calculates the linear regression slope and intercept for the axis, determines geometric properties of the grid vertices, and computes rotation angles needed to align the image. The optimal angle is found by minimizing the error across all computed angles, and the image is rotated accordingly.

Raises:

ValueError – If the axis is not 0 (row-wise) or 1 (column-wise).

Parameters:

image (ImageGridHandler) – The arr grid image object to be aligned.

Returns:

The rotated grid image object after alignment.

Return type:

ImageGridHandler

!!! abstract “Usage Documentation”

[model_copy](../concepts/models.md#model-copy)

Returns a copy of the model.

!!! note

The underlying instance’s [__dict__][object.__dict__] attribute is copied. This might have unexpected side effects if you store anything in it, on top of the model fields (e.g. the value of [cached properties][functools.cached_property]).

Parameters:

• update (Mapping[str, Any] | None) – Values to change/add in the new model. Note: the data is not validated before creating the new model. You should trust this data.

• deep (bool) – Set to True to make a deep copy of the model.

Generate a dictionary representation of the model, optionally specifying which fields to include or exclude.

Parameters:

• mode (Literal['json', 'python'] | str) – The mode in which to_python should run. If mode is ‘json’, the output will only contain JSON serializable types. If mode is ‘python’, the output may contain non-JSON-serializable Python objects.

Returns:

A JSON string representation of the model.

Return type:

str

model_post_init(_BaseOperation__context: Any) → None

Initialize logging and memory tracking after model construction.

Replaces the legacy __init__ body: creates the per-class logger and, when that logger is enabled for INFO level or higher, starts tracemalloc so per-operation memory usage can be logged.

Parameters:

• __context – Pydantic post-init context (unused).

• _BaseOperation__context (Any)

Return type:

None

to_json(filepath: str | Path | None = None) → str | None

Serialize this operation to JSON.

Captures the operation as a {"class", "params"} envelope: params is model_dump(mode="json") (every declared field, including nested operations and raw arrays; PrivateAttr state such as loggers and timing is excluded automatically), and class records the concrete class name so from_json() can rebuild the right subclass. This mirrors ImagePipeline.to_json().

Parameters:

filepath (str | Path | None) – Optional path to write the JSON to. When None, the JSON string is returned instead. Accepts a str or Path.

Returns:

The JSON string when filepath is None, otherwise None.

Return type:

str | None

Example

>>> import tempfile
>>> from pathlib import Path
>>> from phenotypic.detect import OtsuDetector
>>> from phenotypic.sdk_ import CONFIG_SUFFIX_OPERATION, ensure_typed_json_suffix
>>> with tempfile.TemporaryDirectory() as d:
...     p = Path(d) / "op.json"
...     saved = ensure_typed_json_suffix(p, CONFIG_SUFFIX_OPERATION)
...     OtsuDetector(ignore_zeros=True).to_json(p)
...     loaded = OtsuDetector.from_json(saved)
>>> loaded.ignore_zeros
True

widget(image: Image | None = None, show: bool = False) → Widget

Return type:

ipywidgets.Widget

Raises:

ImportError – If ipywidgets or IPython are not installed.

class phenotypic.grid.ManualGridFinder(*, nrows: Annotated[int, TuneSpec(low=None, high=None, step=None, log=False, categories=None, tunable=False)] = 0, ncols: Annotated[int, TuneSpec(low=None, high=None, step=None, log=False, categories=None, tunable=False)] = 0, row_edges: list[int], col_edges: list[int])

Bases: GridFinder

A GridFinder implementation where users directly specify grid row and column coordinates.

This class allows for complete manual control over grid placement by accepting explicit row and column edge coordinates. No optimization or automatic calculation is performed - the grid is defined exactly as specified by the user.

nrows

Number of rows in the grid (derived from row_edges).

Type:

int

ncols

Number of columns in the grid (derived from col_edges).

Type:

int

row_edges

Sorted row edge coordinates defining grid rows.

Type:

list[int]

col_edges

Sorted column edge coordinates defining grid columns.

Type:

list[int]

Parameters:

• row_edges (list[int]) – Row edge coordinates. Length should be nrows + 1. Example: [0, 100, 200, 300] defines 3 rows. A list, tuple, or np.ndarray is accepted; values are cast to int and sorted ascending.

• col_edges (list[int]) – Column edge coordinates. Length should be ncols + 1. Example: [0, 80, 160, 240, 320] defines 4 columns. A list, tuple, or np.ndarray is accepted; values are cast to int and sorted ascending.

• nrows (Annotated[int, TuneSpec(low=None, high=None, step=None, log=False, categories=None, tunable=False)])

• ncols (Annotated[int, TuneSpec(low=None, high=None, step=None, log=False, categories=None, tunable=False)])

Raises:

ValueError – If row_edges or col_edges have fewer than 2 elements.

Example

Create a 3x4 grid with specific coordinates:

>>> import numpy as np
>>> from phenotypic.grid import ManualGridFinder
>>> # Create a 3x4 grid with specific coordinates
>>> row_edges = np.array([0, 100, 200, 300])  # 3 rows
>>> col_edges = np.array([0, 80, 160, 240, 320])  # 4 columns
>>> finder = ManualGridFinder(row_edges=row_edges, col_edges=col_edges)
>>> grid_info = finder.measure(image)

classmethod __get_pydantic_json_schema__(core_schema: CoreSchema, handler: GetJsonSchemaHandler, /) → JsonSchemaValue

Hook into generating the model’s JSON schema.

Parameters:

• core_schema (CoreSchema) – A pydantic-core CoreSchema. You can ignore this argument and call the handler with a new CoreSchema, wrap this CoreSchema ({‘type’: ‘nullable’, ‘schema’: current_schema}), or just call the handler with the original schema.

• handler (GetJsonSchemaHandler) – Call into Pydantic’s internal JSON schema generation. This will raise a pydantic.errors.PydanticInvalidForJsonSchema if JSON schema generation fails. Since this gets called by BaseModel.model_json_schema you can override the schema_generator argument to that function to change JSON schema generation globally for a type.

Returns:

A JSON schema, as a Python object.

Return type:

JsonSchemaValue

classmethod __pydantic_init_subclass__(**kwargs: Any) → None

Populate field descriptions from the subclass docstring.

Runs once per concrete subclass after pydantic has built its model. Copies parameter descriptions parsed from the Google-style Args: docstring block onto each field’s description slot so they surface in model_json_schema() — the machine-readable contract used by downstream tooling (e.g. an MCP server).

Parameters:

**kwargs (Any) – Class-keyword arguments forwarded by pydantic.

Return type:

None

classmethod __pydantic_on_complete__() → None

This is called once the class and its fields are fully initialized and ready to be used.

This typically happens when the class is created (just before [__pydantic_init_subclass__()][pydantic.main.BaseModel.__pydantic_init_subclass__] is called on the superclass), except when forward annotations are used that could not immediately be resolved. In that case, it will be called later, when the model is rebuilt automatically or explicitly using [model_rebuild()][pydantic.main.BaseModel.model_rebuild].

Return type:

None

classmethod construct(_fields_set: set[str] | None = None, **values: Any) → Self

Parameters:

• _fields_set (set[str] | None)

• values (Any)

Return type:

Self

classmethod from_json(json_data: str | Path | dict) → BaseOperation

Reconstruct an operation from JSON written by to_json().

Accepts a JSON string, a path to a JSON file, or a pre-parsed envelope dict (same input handling as ImagePipeline.from_json()). Polymorphic: ImageOperation.from_json(path) returns whatever concrete operation the file holds. When called on a narrower subclass, the resolved class must be a subclass of it, else a TypeError is raised.

Parameters:

json_data (str | Path | dict) – A JSON string, path to a JSON file, or envelope dict.

Returns:

The reconstructed operation instance.

Raises:

• AttributeError – If the recorded class cannot be resolved in the phenotypic namespace.

• TypeError – If called on a concrete subclass and the file holds a class that is not a subclass of it.

Return type:

BaseOperation

Example

>>> import tempfile
>>> from pathlib import Path
>>> from phenotypic.abc_ import ImageOperation
>>> from phenotypic.detect import OtsuDetector
>>> with tempfile.TemporaryDirectory() as d:
...     p = Path(d) / "op.json"
...     OtsuDetector().to_json(p)
...     loaded = ImageOperation.from_json(p)  # polymorphic
>>> type(loaded).__name__
'OtsuDetector'

classmethod from_orm(obj: Any) → Self

Parameters:

obj (Any)

Return type:

Self

classmethod model_construct(_fields_set: set[str] | None = None, **values: Any) → Self

Creates a new instance of the Model class with validated data.

Creates a new model setting __dict__ and __pydantic_fields_set__ from trusted or pre-validated data. Default values are respected, but no other validation is performed.

!!! note

model_construct() generally respects the model_config.extra setting on the provided model. That is, if model_config.extra == ‘allow’, then all extra passed values are added to the model instance’s __dict__ and __pydantic_extra__ fields. If model_config.extra == ‘ignore’ (the default), then all extra passed values are ignored. Because no validation is performed with a call to model_construct(), having model_config.extra == ‘forbid’ does not result in an error if extra values are passed, but they will be ignored.

Parameters:

• _fields_set (set[str] | None) – A set of field names that were originally explicitly set during instantiation. If provided, this is directly used for the [model_fields_set][pydantic.BaseModel.model_fields_set] attribute. Otherwise, the field names from the values argument will be used.

• values (Any) – Trusted or pre-validated data dictionary.

Returns:

A new instance of the Model class with validated data.

Return type:

Self

classmethod model_json_schema(by_alias: bool = True, ref_template: str = '#/$defs/{model}', schema_generator: type[~pydantic.json_schema.GenerateJsonSchema] = <class 'pydantic.json_schema.GenerateJsonSchema'>, mode: ~typing.Literal['validation', 'serialization'] = 'validation', *, union_format: ~typing.Literal['any_of', 'primitive_type_array'] = 'any_of') → dict[str, Any]

Generates a JSON schema for a model class.

Parameters:

• by_alias (bool) – Whether to use attribute aliases or not.

• ref_template (str) – The reference template.

• union_format (Literal['any_of', 'primitive_type_array']) –

  The format to use when combining schemas from unions together. Can be one of:

  • ’any_of’: Use the [anyOf](https://json-schema.org/understanding-json-schema/reference/combining#anyOf)

  keyword to combine schemas (the default). - ‘primitive_type_array’: Use the [type](https://json-schema.org/understanding-json-schema/reference/type) keyword as an array of strings, containing each type of the combination. If any of the schemas is not a primitive type (string, boolean, null, integer or number) or contains constraints/metadata, falls back to any_of.

• schema_generator (type[GenerateJsonSchema]) – To override the logic used to generate the JSON schema, as a subclass of GenerateJsonSchema with your desired modifications

• mode (Literal['validation', 'serialization']) – The mode in which to generate the schema.

Returns:

The JSON schema for the given model class.

Return type:

dict[str, Any]

classmethod model_parametrized_name(params: tuple[type[Any], ...]) → str

Compute the class name for parametrizations of generic classes.

This method can be overridden to achieve a custom naming scheme for generic BaseModels.

Parameters:

params (tuple[type[Any], ...]) – Tuple of types of the class. Given a generic class Model with 2 type variables and a concrete model Model[str, int], the value (str, int) would be passed to params.

Returns:

String representing the new class where params are passed to cls as type variables.

Raises:

TypeError – Raised when trying to generate concrete names for non-generic models.

Return type:

str

Try to rebuild the pydantic-core schema for the model.

This may be necessary when one of the annotations is a ForwardRef which could not be resolved during the initial attempt to build the schema, and automatic rebuilding fails.

Parameters:

• raise_errors (bool) – Whether to raise errors, defaults to True.

• _parent_namespace_depth (int) – The depth level of the parent namespace, defaults to 2.

• _types_namespace (MappingNamespace | None) – The types namespace, defaults to None.

Returns:

model_copy(*, update: Mapping[str, Any] | None = None, deep: bool = False) → Self

!!! abstract “Usage Documentation”

[model_copy](../concepts/models.md#model-copy)

Returns a copy of the model.

!!! note

The underlying instance’s [__dict__][object.__dict__] attribute is copied. This might have unexpected side effects if you store anything in it, on top of the model fields (e.g. the value of [cached properties][functools.cached_property]).

Parameters:

• update (Mapping[str, Any] | None) – Values to change/add in the new model. Note: the data is not validated before creating the new model. You should trust this data.

• deep (bool) – Set to True to make a deep copy of the model.

[model_dump](../concepts/serialization.md#python-mode)

Generate a dictionary representation of the model, optionally specifying which fields to include or exclude.

Parameters:

• mode (Literal['json', 'python'] | str) – The mode in which to_python should run. If mode is ‘json’, the output will only contain JSON serializable types. If mode is ‘python’, the output may contain non-JSON-serializable Python objects.

• include (set[int] | set[str] | Mapping[int, set[int] | set[str] | Mapping[int, IncEx | bool] | Mapping[str, IncEx | bool] | bool] | Mapping[str, set[int] | set[str] | Mapping[int, IncEx | bool] | Mapping[str, IncEx | bool] | bool] | None) – A set of fields to include in the output.

• exclude (set[int] | set[str] | Mapping[int, set[int] | set[str] | Mapping[int, IncEx | bool] | Mapping[str, IncEx | bool] | bool] | Mapping[str, set[int] | set[str] | Mapping[int, IncEx | bool] | Mapping[str, IncEx | bool] | bool] | None) – A set of fields to exclude from the output.

• context (Any | None) – Additional context to pass to the serializer.

• by_alias (bool | None) – Whether to use the field’s alias in the dictionary key if defined.

• exclude_unset (bool) – Whether to exclude fields that have not been explicitly set.

• exclude_defaults (bool) – Whether to exclude fields that are set to their default value.

• exclude_none (bool) – Whether to exclude fields that have a value of None.

• exclude_computed_fields (bool) – Whether to exclude computed fields. While this can be useful for round-tripping, it is usually recommended to use the dedicated round_trip parameter instead.

• round_trip (bool) – If True, dumped values should be valid as input for non-idempotent types such as Json[T].

• warnings (bool | Literal['none', 'warn', 'error']) – How to handle serialization errors. False/”none” ignores them, True/”warn” logs errors, “error” raises a [PydanticSerializationError][pydantic_core.PydanticSerializationError].

• serialize_as_any (bool) – Whether to serialize fields with duck-typing serialization behavior.

Returns:

A dictionary representation of the model.

!!! abstract “Usage Documentation”

[model_dump_json](../concepts/serialization.md#json-mode)

Generates a JSON representation of the model using Pydantic’s to_json method.

Parameters:

• indent (int | None) – Indentation to use in the JSON output. If None is passed, the output will be compact.

• ensure_ascii (bool) – If True, the output is guaranteed to have all incoming non-ASCII characters escaped. If False (the default), these characters will be output as-is.

• include (set[int] | set[str] | Mapping[int, set[int] | set[str] | Mapping[int, IncEx | bool] | Mapping[str, IncEx | bool] | bool] | Mapping[str, set[int] | set[str] | Mapping[int, IncEx | bool] | Mapping[str, IncEx | bool] | bool] | None) – Field(s) to include in the JSON output.

• exclude (set[int] | set[str] | Mapping[int, set[int] | set[str] | Mapping[int, IncEx | bool] | Mapping[str, IncEx | bool] | bool] | Mapping[str, set[int] | set[str] | Mapping[int, IncEx | bool] | Mapping[str, IncEx | bool] | bool] | None) – Field(s) to exclude from the JSON output.

• context (Any | None) – Additional context to pass to the serializer.

• by_alias (bool | None) – Whether to serialize using field aliases.

• exclude_unset (bool) – Whether to exclude fields that have not been explicitly set.

• exclude_defaults (bool) – Whether to exclude fields that are set to their default value.

• exclude_none (bool) – Whether to exclude fields that have a value of None.

• exclude_computed_fields (bool) – Whether to exclude computed fields. While this can be useful for round-tripping, it is usually recommended to use the dedicated round_trip parameter instead.

• round_trip (bool) – If True, dumped values should be valid as input for non-idempotent types such as Json[T].

• warnings (bool | Literal['none', 'warn', 'error']) – How to handle serialization errors. False/”none” ignores them, True/”warn” logs errors, “error” raises a [PydanticSerializationError][pydantic_core.PydanticSerializationError].

• fallback (Callable[[Any], Any] | None) – A function to call when an unknown value is encountered. If not provided, a [PydanticSerializationError][pydantic_core.PydanticSerializationError] error is raised.

• serialize_as_any (bool) – Whether to serialize fields with duck-typing serialization behavior.

Returns:

A JSON string representation of the model.

Return type:

str

model_post_init(_BaseOperation__context: Any) → None

Initialize logging and memory tracking after model construction.

Replaces the legacy __init__ body: creates the per-class logger and, when that logger is enabled for INFO level or higher, starts tracemalloc so per-operation memory usage can be logged.

Parameters:

• __context – Pydantic post-init context (unused).

• _BaseOperation__context (Any)

Return type:

None

to_json(filepath: str | Path | None = None) → str | None

Serialize this operation to JSON.

Captures the operation as a {"class", "params"} envelope: params is model_dump(mode="json") (every declared field, including nested operations and raw arrays; PrivateAttr state such as loggers and timing is excluded automatically), and class records the concrete class name so from_json() can rebuild the right subclass. This mirrors ImagePipeline.to_json().

Parameters:

filepath (str | Path | None) – Optional path to write the JSON to. When None, the JSON string is returned instead. Accepts a str or Path.

Returns:

The JSON string when filepath is None, otherwise None.

Return type:

str | None

Example

>>> import tempfile
>>> from pathlib import Path
>>> from phenotypic.detect import OtsuDetector
>>> from phenotypic.sdk_ import CONFIG_SUFFIX_OPERATION, ensure_typed_json_suffix
>>> with tempfile.TemporaryDirectory() as d:
...     p = Path(d) / "op.json"
...     saved = ensure_typed_json_suffix(p, CONFIG_SUFFIX_OPERATION)
...     OtsuDetector(ignore_zeros=True).to_json(p)
...     loaded = OtsuDetector.from_json(saved)
