datadings.reader.zipfile module

class datadings.reader.zipfile.ZipFileReader(path: str | ~pathlib.Path, patterns: ~typing.Sequence[str | ~pathlib.Path] = '{LABEL}/**', labels=None, numeric_labels=True, initfun: ~typing.Callable = <function noop>, convertfun: ~typing.Callable = <function noop>, include=(), exclude=(), separator='\t')

Bases: ListReader

Reader that reads files from a ZIP file.

Note

Functionally identical to the DirectoryReader, expect it reads from ZIP files instead of filesystem directories. Please refer to its documentation for more detailed explanations.

Parameters:

• patterns – One or more search patterns.

• labels – Optional. List of labels in desired order, or path to file with one label per line. If None, get "label" keys from samples, if any, and sort.

• numeric_labels – If true, convert labels to numeric index to list of all labels.

• initfun – Callable initfun(sample: dict) to modify samples in-place during initialization.

• convertfun – Callable convertfun(sample: dict) to modify samples in-place before they are returned.

• include – Set of inclusion patterns.

• exclude – Set of exclusion patterns.

• separator – Separator string for file patterns.
