TFX artifact used for orchestration.

tfx.types.Artifact(
    mlmd_artifact_type: Optional[metadata_store_pb2.ArtifactType] = None

Used in the tutorials

This is used for type-checking and inter-component communication. Currently, it wraps a tuple of (ml_metadata.proto.Artifact, ml_metadata.proto.ArtifactType) with additional property accessors for internal state.

A user may create a subclass of Artifact and override the TYPE_NAME property with the type for this artifact subclass. Users of the subclass may then omit the "type_name" field when construction the object.

A user may specify artifact type-specific properties for an Artifact subclass by overriding the PROPERTIES dictionary, as detailed below.

mlmd_artifact_type Proto message defining the underlying ArtifactType. Optional and intended for internal use.
