class documentation

class LegacyFiftyOneDataset(Dataset): (source)

Legacy disk representation of an entire fiftyone.core.dataset.Dataset stored on disk in a serialized JSON format along with its source media.

Datasets of this type are read/written in the following format:

<dataset_dir>/
    metadata.json
    samples.json
    data/
        <filename1>.<ext>
        <filename2>.<ext>
        ...
    annotations/
        <anno_key1>.json
        <anno_key2>.json
        ...
    brain/
        <brain_key1>.json
        <brain_key2>.json
        ...
    evaluations/
        <eval_key1>.json
        <eval_key2>.json
        ...

where metadata.json is a JSON file containing metadata associated with the dataset, samples.json is a JSON file containing a serialized representation of the samples in the dataset, annotations/ contains any serialized fiftyone.core.annotations.AnnotationResults, brain/ contains any serialized fiftyone.core.brain.BrainResults, and evaluations/ contains any serialized fiftyone.core.evaluations.EvaluationResults.

Video datasets have an additional frames/ directory that contains a serialized representation of the frame labels for each video in the dataset.
