Bases: ImagePipeline

Marker class for pre-built, validated image processing pipelines from the PhenoTypic team.

PrefabPipeline is a specialized subclass of ImagePipeline that distinguishes “official” pre-built pipelines maintained by the PhenoTypic development team from user-created custom pipelines. It serves as a marker class (no additional functionality) that signals “this pipeline is validated, documented, and recommended for specific use cases in microbe colony phenotyping.”

What is PrefabPipeline?

PrefabPipeline is NOT an operation ABC and does NOT inherit from BaseOperation. Instead, it’s a subclass of ImagePipeline that:

Is a marker class: Inherits all ImagePipeline functionality unchanged; no new methods.
Indicates official status: Subclasses of PrefabPipeline are pre-built, validated pipelines with documented performance, parameter settings, and recommended use cases.
Enables classification: Code can distinguish official pipelines (isinstance(obj, PrefabPipeline)) from user-defined pipelines for documentation, discovery, or defaulting.
Provides templates: Each PrefabPipeline subclass is a complete processing workflow (enhancement, detection, refinement, measurement) ready to use out-of-the-box.

Quick Decision Guide: PrefabPipeline vs Custom ImagePipeline

Use PrefabPipeline for standard colony phenotyping on agar plates with validated workflows
Use custom ImagePipeline for novel imaging scenarios, optimization experiments, or specialized workflows
Start with PrefabPipeline to understand the pipeline structure, then customize via parameter tuning
Clone and modify a PrefabPipeline subclass when you need significant algorithm changes
Combine multiple PrefabPipelines sequentially for complex multi-stage workflows

Available PrefabPipeline Subclasses

The PhenoTypic team maintains several pre-built pipelines optimized for different imaging scenarios:

[HeavyOtsuPipeline](src/phenotypic/prefab/_heavy_otsu_pipeline.py): Multi-layer Otsu detection with aggressive refinement. Robust detection on challenging images (uneven lighting, varied sizes). Computationally expensive.
[HeavyWatershedPipeline](src/phenotypic/prefab/_heavy_watershed_pipeline.py): Watershed segmentation for separated colonies. Handles closely-spaced or merged colonies. Very expensive; for small batches or deep analysis.
[RoundPeaksPipeline](src/phenotypic/prefab/_round_peaks_pipeline.py): Peak detection for circular, well-separated colonies. Fast and suitable for high-throughput screening of early-time-point growth.
[GridSectionPipeline](src/phenotypic/prefab/_grid_section_pipeline.py): Per-well section extraction and fine-grained analysis. Moderate cost; enables per-well quality control and segmentation.
[FilamentousFungiPipeline](src/phenotypic/prefab/_filamentous_fungi_pipeline.py): Two-stage filamentous fungi detection with optional Dijkstra branch reconnection. For irregular spreading colonies.

When to use PrefabPipeline vs Custom ImagePipeline

Use PrefabPipeline if: - You’re analyzing colony growth on agar plates (the intended use case). - You want an immediately usable, tested workflow without configuration. - You want to reproduce results matching published benchmarks or team documentation. - You need a baseline for custom extensions (subclass or copy and modify).
Create a custom ImagePipeline if: - Your imaging scenario is novel (unusual plate format, different organisms, special preparation). - You want to experiment with different detector/refiner/measurement combinations. - You have labeled ground truth and want to optimize parameters for your specific images. - You need pipeline extensions (custom operations not in standard library).

Using a PrefabPipeline

PrefabPipeline subclasses are used exactly like ImagePipeline:

from phenotypic import Image, GridImage
from phenotypic.prefab import HeavyOtsuPipeline

# Load image(s)
image = GridImage.imread('plate.jpg', nrows=8, ncols=12)

# Instantiate and apply pipeline
pipeline = HeavyOtsuPipeline()
result = pipeline.apply(image)  # or .operate([image])

# Access results
colonies = result.objects
measurements = result.measurements
print(f"Detected: {len(colonies)} colonies")
print(f"Measurements shape: {measurements.shape}")

Customizing a PrefabPipeline

PrefabPipelines accept tunable parameters in __init__() to adapt to your images without rebuilding the pipeline structure:

from phenotypic.prefab import HeavyOtsuPipeline

# Use defaults (recommended for most cases)
pipeline1 = HeavyOtsuPipeline()

# Tune for noisier images
pipeline2 = HeavyOtsuPipeline(
    gaussian_sigma=7,                    # Stronger blur
    small_object_min_size=150,           # More aggressive noise removal
    border_remover_size=2                # Remove more edge objects
)

# Parameters are typically named after the algorithm or parameter they control.
# See pipeline docstring for available parameters and typical values.

When Parameters Fail: Creating a Custom Pipeline

If PrefabPipeline parameter tuning doesn’t solve your problem:

Analyze failures: Which step fails (detection, refinement, measurement)?

Use pipeline.benchmark=True, verbose=True to trace execution.

Visually inspect intermediate results (detection masks, refined masks).

Create a custom pipeline:

from phenotypic import ImagePipeline
from phenotypic.enhance import GaussianBlur, EnhanceLocalContrast
from phenotypic.detect import CannyDetector  # Different detector
from phenotypic.refine import SmallObjectRemover, MaskFill
from phenotypic.measure import MeasureShape, MeasureColor

# Custom pipeline for your specific use case
custom = ImagePipeline()
custom.add(GaussianBlur(sigma=3))
custom.add(EnhanceLocalContrast())
custom.add(CannyDetector(sigma=1.5, low_threshold=0.1, high_threshold=0.4))
custom.add(SmallObjectRemover(min_size=100))
custom.add(MaskFill())
custom.add(MeasureShape())
custom.add(MeasureColor())

# Test and iterate
result = custom.operate([image])

Share successful custom pipelines: If you develop a successful custom pipeline for a new imaging scenario, consider contributing it as a PrefabPipeline subclass to the project.

Pipeline Composition Pattern

Combine multiple PrefabPipelinesor mix PrefabPipeline with custom operations:

from phenotypic import ImagePipeline
from phenotypic.prefab import HeavyOtsuPipeline, RoundPeaksPipeline
from phenotypic.refine import SmallObjectRemover
from phenotypic.measure import MeasureIntensity

# Combine different detection strategies with shared refinement
pipeline = ImagePipeline()
pipeline.add(HeavyOtsuPipeline())  # First detection attempt
pipeline.add(SmallObjectRemover(min_size=100))  # Noise removal
pipeline.add(MeasureIntensity())  # Measurement

# Apply to image
result = pipeline.apply(image)

Pipeline Serialization Pattern

Save and load pipelines for reproducible batch processing:

from phenotypic.prefab import HeavyOtsuPipeline

# Create, configure, and save
pipeline = HeavyOtsuPipeline(gaussian_sigma=2.0, small_object_min_size=150)
pipeline.to_json('my_colony_pipeline.json')  # Save configuration
# pipeline.to_yaml('my_colony_pipeline.yaml')  # Alternative format

# Load for batch processing (reproducible results)
loaded = HeavyOtsuPipeline.from_json('my_colony_pipeline.json')
results = loaded.operate([image1, image2, image3])

Extending PrefabPipeline

To create a new official PrefabPipeline subclass:

from phenotypic.abc_ import PrefabPipeline
from phenotypic.enhance import GaussianBlur, EnhanceLocalContrast
from phenotypic.detect import OtsuDetector
from phenotypic.refine import SmallObjectRemover
from phenotypic.measure import MeasureShape

class MyCustomPrefabPipeline(PrefabPipeline):
    '''Brief description of when to use this pipeline.'''

    def __init__(self, param1: int = 100, param2: float = 1.5,
                 benchmark: bool = False, verbose: bool = False):
        '''Initialize with tunable parameters.'''
        pipe_cfgs = [
            GaussianBlur(sigma=param2),
            EnhanceLocalContrast(),
            OtsuDetector(),
            SmallObjectRemover(min_size=param1),
        ]
        meas = [MeasureShape()]
        super().__init__(pipe_cfgs=pipe_cfgs, meas=meas, benchmark=benchmark,
                       verbose=verbose)

Notes

Is a marker, not an operation: PrefabPipeline does not inherit from BaseOperation. It’s a convenient subclass of ImagePipeline for classification and discovery.
Inheritance of ImagePipeline features: PrefabPipeline inherits all ImagePipeline functionality: sequential operation chaining, benchmarking, verbose logging, batch processing via .operate(), and serialization via .to_yaml() / .from_yaml().
Parameter tuning via __init__(): Most PrefabPipeline subclasses expose key algorithm parameters in __init__() (e.g., detection threshold, smoothing sigma, refinement shape). Adjust these for your specific images before scaling to large batches.
Benchmarking for profiling: Set benchmark=True when instantiating to track execution time and memory usage per operation. Useful for identifying bottlenecks in large batch runs.
Documentation and examples: Each PrefabPipeline subclass is documented with use cases, typical parameters, performance characteristics, and example code. Check the subclass docstring for guidance.
Not for operations: Use PrefabPipeline only for complete pipelines. For individual operations (detection, enhancement, measurement), use operation ABCs directly.

Examples

Quick start: Detect colonies with HeavyOtsuPipeline:

>>> from phenotypic import GridImage
>>> from phenotypic.prefab import HeavyOtsuPipeline
>>> # Load a 96-well plate image
>>> image = GridImage.imread('agar_plate.jpg', nrows=8, ncols=12)
>>> # Use the pre-built, validated pipeline
>>> pipeline = HeavyOtsuPipeline()
>>> result = pipeline.apply(image)
>>> # Access results
>>> print(f"Detected {len(result.objects)} colonies")
>>> print(f"Measurements: {result.measurements.columns.tolist()}")

Batch processing multiple plates with a PrefabPipeline:

>>> from phenotypic import GridImage
>>> from phenotypic.prefab import HeavyOtsuPipeline
>>> import glob
>>> # Load multiple plate images
>>> image_paths = glob.glob('batch_*.jpg')
>>> images = [GridImage.imread(p, nrows=8, ncols=12)
...           for p in image_paths]
>>> # Create pipeline (reusable for all images)
>>> pipeline = HeavyOtsuPipeline(benchmark=True)
>>> # Batch process
>>> results = pipeline.operate(images)
>>> # Collect results
>>> for i, result in enumerate(results):
...     print(f"Image {i}: {len(result.objects)} colonies")
...     print(f"Measurements shape: {result.measurements.shape}")

Customizing pipeline parameters for difficult images:

>>> from phenotypic import GridImage
>>> from phenotypic.prefab import HeavyOtsuPipeline
>>> image = GridImage.imread('noisy_plate.jpg', nrows=8, ncols=12)
>>> # Increase smoothing and noise removal for difficult images
>>> pipeline = HeavyOtsuPipeline(
...     gaussian_sigma=8,                      # Stronger blur
...     small_object_min_size=200,             # Aggressive noise removal
...     border_remover_size=2                  # More border filtering
... )
>>> result = pipeline.apply(image)
>>> print(f"Robust detection: {len(result.objects)} colonies")

Comparing PrefabPipeline vs custom pipeline:

>>> from phenotypic import GridImage, ImagePipeline
>>> from phenotypic.prefab import HeavyOtsuPipeline
>>> from phenotypic.detect import CannyDetector
>>> from phenotypic.refine import SmallObjectRemover
>>> image = GridImage.imread('plate.jpg', nrows=8, ncols=12)
>>> # Option 1: Use pre-built validated pipeline
>>> prefab = HeavyOtsuPipeline()
>>> result1 = prefab.apply(image)
>>> # Option 2: Create custom pipeline for comparison
>>> custom = ImagePipeline()
>>> from phenotypic.enhance import GaussianBlur
>>> custom.add(GaussianBlur(sigma=2))
>>> custom.add(CannyDetector(sigma=1.5, low_threshold=0.1, high_threshold=0.4))
>>> custom.add(SmallObjectRemover(min_size=100))
>>> result2 = custom.apply(image)
>>> # Compare results
>>> print(f"Prefab: {len(result1.objects)}, Custom: {len(result2.objects)}")

classmethod from_json(json_data: str | Path | dict, benchmark: bool = False, verbose: bool = False) → PrefabPipeline[source]#

Deserialize a PrefabPipeline from JSON.

PrefabPipeline subclasses build their ops/meas inside __init__, so the base from_json (which passes ops= directly) would conflict. This override deserializes via ImagePipeline and re-tags the instance as the correct PrefabPipeline subclass.

Parameters:

json_data (str | Path | dict) – A JSON string, path to a JSON file, or a pre-parsed dict.
benchmark (bool) – Whether to enable benchmarking for the pipeline.
verbose (bool) – Whether to enable verbose output.

Returns:

A PrefabPipeline (or subclass) instance with the loaded configuration.

Return type:

PrefabPipeline

__copy__() → Self#

Returns a shallow copy of the model.

Return type:: Self

__deepcopy__(memo: dict[int, Any] | None = None) → Self#

Returns a deep copy of the model.

Parameters:: memo (dict[int, Any] | None)
Return type:: Self

__del__()#: Automatically stop tracemalloc when the object is deleted.

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

__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]

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

__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:: str

__rich_repr__() → RichReprResult#

Used by Rich (https://rich.readthedocs.io/en/stable/pretty.html) to pretty print objects.

Return type:: RichReprResult

__str__() → str#

Return a JSON-formatted string representation of the pipeline.

The generated JSON string provides a structured representation of the object’s current state, including its operations and measurements. This output can be used for logging, debugging, or to recreate the object’s configuration in another context.

Returns:: A JSON-formatted string that encodes the object’s current configuration in a human-readable manner. This includes the phenotypic version, pipeline name, description, and the lists of operations and measurements.
Return type:: str

analyze(df: pandas.DataFrame) → pandas.DataFrame#

Run the analysis chain (filters then model) against an aggregate frame.

Applies each filter in order — each transforms a DataFrame into another DataFrame — then runs the configured terminal model to produce a fit summary (typically one row per group).

The expected input is the post-applied, aggregated DataFrame the CLI seeds into measurements.parquet. analyze does not apply post itself: by default measure() runs self._post before returning, and the CLI applies post explicitly to a copy of the aggregated master before invoking analyze. Callers passing apply_post=False to measure() are responsible for applying post (or accepting that filters/model see pre-post data) before calling analyze.

Parameters:

df (pandas.DataFrame) – The aggregate measurements DataFrame.

Returns:

The model-fit output (one row per group, plus shared: MODEL_METRICS columns for fit quality).

Return type:

pd.DataFrame

Raises:

ValueError – If no model is configured. Configure via set_model() (or pass model= at construction).

apply(image: Image, inplace: bool = False, reset: bool | None = None) → GridImage | Image#

The class provides an interface to process and apply a series of operations on an Image. The operations are maintained in a queue and executed sequentially when applied to the given Image.

Parameters:

image (Image) – The arr Image to be processed. The type Image refers to an instance of the Image object to which transformations are applied.
inplace (bool, optional) – A flag indicating whether to apply the transformations directly on the provided Image (True) or create a copy of the Image before performing transformations (False). Defaults to False.
reset (bool, optional) – Whether to reset the image before applying the pipeline. If None (default), uses the pipeline’s reset setting from __init__. If explicitly set to True or False, overrides the pipeline setting.

Return type:

Union[GridImage, Image]

apply_and_measure(image: Image, inplace: bool = False, reset: bool | None = None, include_metadata: bool = True, apply_post: bool = True) → pd.DataFrame#

Applies processing to the given image and measures the results.

This function first applies a processing method to the supplied image, adjusting it based on the given parameters. After processing, the resulting image is measured, and a DataFrame containing the measurement data is returned.

Parameters:

image (Image) – The image to process and measure.
inplace (bool) – Whether to modify the original image directly or work on a copy. Default is False.
reset (bool, optional) – Whether to reset any previous processing on the image before applying the current method. If None (default), uses the pipeline’s reset setting. If explicitly set, overrides the pipeline setting.
include_metadata (bool) – Whether to include metadata in the measurement results. Default is True.
apply_post (bool) – Forwarded to measure(). When False, the returned DataFrame skips PostMeasurement ops. Defaults to True.

Returns:

A DataFrame containing measurement data for the processed image.

Return type:

pd.DataFrame

apply_napari(image: Image, inplace: bool = False, reset: bool | None = None, viewer: napari.Viewer | None = None) → NapariPipelineResult#

Apply the pipeline and progressively add layers to a napari viewer.

Creates (or reuses) a napari viewer and adds the original image layers as a baseline, then adds the modified layer after each operation completes. Layer names follow the pattern {step:02d}_{OperationName}_{accessor}.

Parameters:

image (Image) – The input image to process.
inplace (bool) – If True the image is modified in place; otherwise a copy is made first. Defaults to False.
reset (bool | None) – Whether to reset the image before applying operations. None (default) uses the pipeline-level setting.
viewer (napari.Viewer | None) – An existing napari viewer to add layers to. If None (default), a new viewer is created.

Returns:

Named tuple with the final image and the napari viewer reference.

Return type:

NapariPipelineResult

Raises:

ImportError – If napari is not installed.

apply_with_intermediates(image: Image, inplace: bool = False, reset: bool | None = None, output_dir: str | Path | None = None, *, full_layers: bool = False) → IntermediateResult#

Apply the pipeline and capture a snapshot of the image after each operation.

Behaves identically to apply() (respecting inplace, reset, benchmark timing, and verbose/tqdm progress) but additionally records the image state after every operation completes.

Parameters:

image (Image) – The input image to process.
inplace (bool) – If True the image is modified in place; otherwise a copy is made first. Defaults to False.
reset (Optional[bool]) – Whether to reset the image before applying operations. None (default) uses the pipeline-level setting.
output_dir (Optional[Union[str, Path]]) – Optional directory path. When provided, each intermediate image is persisted to an HDF5 file inside this directory (created automatically) and the corresponding dict value is set to None to conserve memory. When None, intermediates are kept in memory as Image copies.
full_layers (bool) – When True and output_dir is set, each non-read-only operation’s full image state is written as a complete schema-v2 snapshot via save2hdf5 (all layers + class/grid metadata) instead of the delta layout. Used by the builder’s node-preview cache so any node’s HDF reconstructs a faithful Image/GridImage. Defaults to False.

Returns:

A named tuple containing the final image and a dictionary mapping operation names to intermediate snapshots (or None when output_dir is used).

Return type:

IntermediateResult

benchmark_results() → pandas.DataFrame#

Return execution times and memory usage for operations and measurements.

This method should be called after applying the pipeline on an image to get the execution times and memory consumption of the different processes.

When an operation is itself an ImagePipelineCore (nested pipeline), its sub-operations are expanded as indented sub-rows beneath the parent entry with names like "ParentOp > ChildOp".

Returns:

A DataFrame with columns Process Type,: Process Name, Execution Time (s), Memory Delta (MB), and RSS After (MB).

Return type:

pd.DataFrame

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

Parameters:

_fields_set (set[str] | None)
values (Any)

Return type:

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:

measure(image: Image, include_metadata: bool = True, apply_post: bool = True) → pd.DataFrame#

Measures properties of a given image and optionally includes metadata. The method performs measurements using a set of predefined measurement operations. If benchmarking is enabled, the execution time of each measurement is recorded. When verbose mode is active, detailed logging of the measurement process is displayed. A progress bar is used to track progress if the tqdm library is available.

Parameters:

image (Image) – The image object for which measurements are performed. It must support the info method and optionally a grid or objects attribute.
include_metadata (bool, optional) – Indicates whether metadata should be included in the measurements. Defaults to True.
apply_post (bool, optional) – Whether to apply the configured PostMeasurement operations to the merged frame before returning. Defaults to True. Pass False to obtain the pre-post merged DataFrame — useful when the caller (e.g. the CLI) wants to persist a clean copy and apply post separately.

Returns:

A DataFrame containing the results of all performed measurements combined: on the same index. Columns are ordered as [metadata] -> [measurements] -> [MetadataImage_] -> [info block]: user/experimental Metadata* columns first (in canonical REMBI order, present only when include_metadata is True), then the measurement columns, then the framework MetadataImage_* bookkeeping block (per-image provenance: UUID, ImageName, BitDepth, …), then the per-object image-info block (Object_Label followed by the Bbox_* / Grid_* geometry columns) last.

Return type:

pd.DataFrame

Raises:

Exception – An exception is raised if a measurement operation fails while being applied to the image.

model_computed_fields = {}#

model_config: ClassVar[ConfigDict] = {'arbitrary_types_allowed': True, 'extra': 'forbid', 'validate_assignment': True, 'validate_by_name': True}#: Configuration for the model, should be a dictionary conforming to [ConfigDict][pydantic.config.ConfigDict].

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

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.

Returns:

New model instance.

Return type:

Self

!!! abstract “Usage Documentation”: [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.

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].

Parameters:: qc (List[QcRecipeEntry] | None) – A list of QcRecipeEntry, or None to clear.
Raises:: TypeError – If qc is neither a list nor None (raised by the _normalize_qc validator on assignment).
Return type:: None

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

Serialize the pipeline configuration to JSON format.

This method captures the pipeline’s operations and measurements. It excludes internal state (pydantic PrivateAttr fields) and pandas DataFrames to keep the serialization clean and focused on reproducible configuration.

Parameters:: filepath (str | Path | None) – Optional path to save the JSON. If None, returns JSON string. Can be a string or Path object.
Returns:: JSON string representation of the pipeline configuration.
