You can give a Tag or a list of Tag.

Examples

tag_bicycle = client.create_tag("bicycle", Target.DATA)
tag_car = client.create_tag("car", Target.DATA)
tag_truck = client.create_tag("truck", Target.DATA)

data.add_tags(tag_bicycle)
data.add_tags([tag_car, tag_truck])

copy

copy()

Description

split

split(
   ratio: float
)

Description

delete

delete()

Description

Delete assets from their dataset

:warning: DANGER ZONE: Be very careful here!

Remove these assets and its annotation from the dataset it belongs

Examples

some_assets = dataset.list_assets()[:10]
some_assets.delete()

download

download(
   target_path: Union[str, Path] = './', force_replace: bool = False,
   max_workers: Optional[int] = None, use_id: bool = False
)

Description

Download this multi asset in given target path

Examples

bunch_of_assets = client.get_dataset("foo_dataset").get_version("first").list_assets()
bunch_of_assets.download('./downloads/')

Arguments

  • target_path (str or Path, optional) : Target path where to download. Defaults to './'.

  • max_workers (int, optional) : Number of max workers used to download. Defaults to os.cpu_count() + 4.

  • force_replace : (bool, optional): Replace an existing file if exists. Defaults to False.

  • use_id (bool, optional) : If true, will download file with id and extension as file name. Defaults to False.

delete_annotations

delete_annotations(
   workers: Optional[List[Worker]] = None
)

Description

Delete all annotations of all these assets: it will erase every shape of every annotation of every asset.

You can give workers on which it will be effectively erased.

:warning: DANGER ZONE: Be careful here !

Examples

multiple_assets.delete_annotations(workers=[my_worker_1, my_worker_2])

Arguments

  • workers (List[Worker], optional) : List of workers on which it will be effectively erased. Defaults to None.

as_list_of_data

as_list_of_data()

Description

Convert a MultiAsset into a List of Data. Assets can come from different Datalake.
This is slower than calling .as_multidata(), so if you know that all your data are coming
from the same datalake, you should call .as_multidata instead

Returns

A list of Data object

as_multidata

as_multidata(
   force_refresh: bool = True
)

Description

Convert a MultiAsset into a MultiData.
Assets must all be in the same datalake to be retrieved.
In case of a dataset with multiple datalake source, you can use .as_list_of_data() that will return a list of data but slower

Arguments

  • force_refresh (bool, optional) : when False, will not refresh data by calling platform.

Returns

a MultiData object
