class datumaro.plugins.data_formats.datumaro.page_mapper.DatumPageMapper(path: str)[source]#

Bases: object

Construct page maps for items and annotations from the JSON file, which are used for the stream importer.

It also provides __iter__() to produce item and annotation dictionaries in stream manner after constructing the page map.

iter_item_ids() → Iterator[str][source]#

property dm_format_version: str | None#: Parse “dm_format_version” section from the given JSON file using the stream json parser

property media_type: MediaType | None#: Parse “media_type” section from the given JSON file using the stream json parser

property ann_types: Set[AnnotationType] | None#: Parse “media_type” section from the given JSON file using the stream json parser

property infos: Dict[str, Any]#: Parse “infos” section from the given JSON file using the stream json parser

property categories: Dict[str, Any]#: Parse “categories” section from the given JSON file using the stream json parser

class datumaro.plugins.data_formats.datumaro.page_mapper.Any(*args, **kwargs)[source]#

Bases: object

Any is compatible with every type.
Any assumed to have all methods.
All values assumed to be instances of Any.

Note that all the above statements are true from the point of view of static type checkers. At runtime, Any should not be used with instance checks.
