put(item)[source]#

get(id, subset=None)[source]#: Provides random access to dataset items.

remove(id, subset=None)[source]#

get_subset(name)[source]#

subsets()[source]#: Enumerates subsets in the dataset. Each subset can be a dataset itself.

infos()[source]#: Returns meta-info of dataset.

categories()[source]#: Returns metainfo about dataset labels.

media_type()[source]#

Returns media type of the dataset items.

All the items are supposed to have the same media type. Supposed to be constant and known immediately after the object construction (i.e. doesn’t require dataset iteration).

ann_types()[source]#: Returns available task type from dataset annotation types.

infos()[source]#: Returns meta-info of dataset.

categories()[source]#: Returns metainfo about dataset labels.

get_subset(name)[source]#

subsets()[source]#: Enumerates subsets in the dataset. Each subset can be a dataset itself.

get(id, subset=None)[source]#: Provides random access to dataset items.

media_type()[source]#

Returns media type of the dataset items.

All the items are supposed to have the same media type. Supposed to be constant and known immediately after the object construction (i.e. doesn’t require dataset iteration).
