uwacan._core.DatasetWrap.load

classmethod DatasetWrap.load(path, lookup_class=True, **kwargs)

Load data from a Zarr file and optionally restore the original class.

This method loads data from a Zarr file and attempts to reconstruct the original class that was used to save the data. The class information is stored in the __uwacan_class__ attribute of the dataset. If the class is found, the method dynamically loads and instantiates it.

Parameters:

pathstr or pathlib.Path

The file path from which to load the data.

lookup_classbool, default=True

If True attempts to restore the original class from the metadata stored in the Zarr file. If False, the called class is used to load the data.

Returns:

objcls or __uwacan_class__

An instance of the class used to save the data (if found in the Zarr file’s metadata), or an instance of the called class.

Notes

• The Zarr file should have the __uwacan_class__ attribute in the dataset’s metadata to allow class reconstruction.

• If the class cannot be found, or if there is an error during dynamic import, the method falls back to using the current class cls to instantiate the object.
