tfds.builder_from_directory

Loads a tfds.core.DatasetBuilder from the given generated dataset path.

tfds.builder_from_directory(
    builder_dir: epath.PathLike,
    file_format: (str | file_adapters.FileFormat | None) = None
) -> dataset_builder.DatasetBuilder

Reconstructs the tfds.core.DatasetBuilder without requiring the original generation code.

From <builder_dir>/features.json it infers the structure (feature names, nested dict,...) and content (image, sequence,...) of the dataset. The serialization format is defined in tfds.features.FeatureConnector in to_json().

builder_dir Path of the directory containing the dataset to read ( e.g. ~/tensorflow_datasets/mnist/3.0.0/).
file_format The desired file format to use for the dataset. If not specified, the default file format in the DatasetInfo is used.

builder tfds.core.DatasetBuilder, builder for dataset at the given path.
