tfds.testing.DummyDatasetCollection

Stay organized with collections Save and categorize content based on your preferences.

Minimal Dataset Collection builder.

all_versions Returns all versions available for the dataset collection.
datasets Returns the datasets included in the collection, ordered by version.

Users will need to overwrite this function when implementing their dataset collection.

The returned dictionary needs to contain the dataset collection versions as keys, and a dictionary of the included TFDS datasets as values.

@property
def datasets(self):
return {
    "1.0.0":
        naming.references_for({
            "yes_no": "yes_no:1.0.0",
            "sst2": "glue/sst:2.0.0",
            "assin2": "assin2:1.0.0",
        }),
    ...
}

Note that the above is equivalent to:

@property
def datasets(self):
return {
    "1.0.0": {
        "yes_no":
            naming.DatasetReference(
                dataset_name="yes_no", version="1.0.0"),
        "sst2":
            naming.DatasetReference(
                dataset_name="glue", config="sst2", version="2.0.0"),
        "assin2":
            naming.DatasetReference(
                dataset_name="assin2", version="1.0.0"),
    },
    ...
}
