dask.array.from_zarr¶

dask.array.from_zarr(url, component=None, storage_options=None, chunks=None, name=None, inline_array=False, **kwargs)[source]¶

Load array from the zarr storage format

See https://zarr.readthedocs.io for details about the format.

Parameters

url: Zarr Array or str or MutableMapping: Location of the data. A URL can include a protocol specifier like s3:// for remote data. Can also be any MutableMapping instance, which should be serializable if used in multiple processes.
component: str or None: If the location is a zarr group rather than an array, this is the subcomponent that should be loaded, something like 'foo/bar'.
storage_options: dict: Any additional parameters for the storage backend (ignored for local paths)
chunks: tuple of ints or tuples of ints: Passed to dask.array.from_array(), allows setting the chunks on initialisation, if the chunking scheme in the on-disc dataset is not optimal for the calculations to follow.
namestr, optional: An optional keyname for the array. Defaults to hashing the input
kwargs:: Passed to zarr.core.Array.
inline_arraybool, default False: Whether to inline the zarr Array in the values of the task graph. See dask.array.from_array() for an explanation.
