ModelCardToolkit provides utilities to generate a ModelCard.

model_card_toolkit.Source] = None )
ModelCardToolkit is a tool for ML practitioners to create Model Cards, documentation for model information such as owners, use cases, training and evaluation data, performance, etc. A Model Card document can be displayed in output formats including HTML, Markdown, etc.
The ModelCardToolkit includes an API designed for a human-in-the-loop process to elaborate the ModelCard. If model training is integrated with ML Metadata (e.g., TFX pipelines), the ModelCardToolkit can further populate ModelCard fields by extract metadata and lineage from the model's MLMD instance.
The ModelCardToolkit organizes the ModelCard assets (e.g., structured data, plots, and UI templates) in a user-specified directory, and updates them incrementally via its API.

export_format( model_card: Optional[Union[

Generates a model card document based on the MCT assets.
The model card document is both returned by this function, as well as saved to output_file.
The ModelCard object, generated from
||The file path of the Jinja template. If not provided, the default template will be used.|
||The file name of the generated model card. If not provided, the default 'model_card.html' will be used. If the file already exists, then it will be overwritten.|
|The model card file content.|
scaffold_assets( json: Optional[Union[Dict[str, Any], str]] = None ) ->
Generates the Model Card Tookit assets.
Assets include the ModelCard proto file, Model Card document, and jinja
template. These are written to the
output_dir declared at
An assets directory is created if one does not already exist.
If the MCT is initialized with a
mlmd_source, it further auto-populates
ModelCard properties and generates plots for model performance and data
distributions. The ModelCard is saved as an Artifact to the
An optional JSON object which can be used to populate fields in the
model card. This can be provided as either a dictionary or a string. If
provided, any fields used here will overwrite fields populated by

update_model_card( model_card: Union[
model_card_toolkit.ModelCard, model_card_pb2.ModelCard] ) -> None
Updates the Proto file in the MCT assets directory.
