Interface ModelJSON

The on-disk format of the model.json file.

TF.js 1.0 always populates the optional fields when writing model.json. Prior versions did not provide those fields.

interface ModelJSON {
    convertedBy?: null | string;
    format?: string;
    generatedBy?: string;
    initializerSignature?: {};
    modelInitializer?: {};
    modelTopology: {};
    signature?: {};
    trainingConfig?: TrainingConfig;
    userDefinedMetadata?: {
        [key: string]: {};
    };
    weightsManifest: WeightsManifestConfig;
}

Properties

Optional convertedBy

convertedBy?: null | string

What library or tool is responsible for converting the original model to this format, applicable only if the model is output by a converter.

Used for debugging purposes. E.g., 'TensorFlow.js Converter v1.0.0'.

A value of null means the model artifacts are generated without any conversion process (e.g., saved directly from a TensorFlow.js tf.LayersModel instance.)

Optional format

format?: string

Hard-coded format name for models saved from TensorFlow.js or converted by TensorFlow.js Converter.

Optional generatedBy

generatedBy?: string

What library is responsible for originally generating this artifact.

Used for debugging purposes. E.g., 'TensorFlow.js v1.0.0'.

Optional initializerSignature

initializerSignature?: {}

Inputs and outputs signature for model initializer.

Type declaration

    Optional modelInitializer

    modelInitializer?: {}

    Initializer for the model.

    Type declaration

      modelTopology

      modelTopology: {}

      Model topology.

      For Keras-style tf.Models, this is a JSON object. For TensorFlow-style models (e.g., SavedModel), this is the JSON encoding of the GraphDef protocol buffer.

      Type declaration

        Optional signature

        signature?: {}

        Inputs and outputs signature for saved model.

        Type declaration

          Optional trainingConfig

          trainingConfig?: TrainingConfig

          Model training configuration.

          Optional userDefinedMetadata

          userDefinedMetadata?: {
              [key: string]: {};
          }

          User-defined metadata about the model.

          Type declaration

          • [key: string]: {}

            weightsManifest

            weightsManifest: WeightsManifestConfig

            Weights manifest.

            The weights manifest consists of an ordered list of weight-manifest groups. Each weight-manifest group consists of a number of weight values stored in a number of paths. See the documentation of WeightsManifestConfig for more details.
