tfds.core.add_data_dir

View source on GitHub

Registers a new default data_dir to search for datasets.

When a tfds.core.DatasetBuilder is created with data_dir=None, TFDS will look in all registered data_dir (including the default one) to load existing datasets.

  • An error is raised if a dataset can be loaded from more than 1 registered data_dir.
  • This only affects reading datasets. Generation always uses the data_dir kwargs when specified or tfds.core.constant.DATA_DIR otherwise.

data_dir New data_dir to register.
