pooch.Pooch.fetch

Pooch.fetch(fname)

Get the absolute path to a file in the local storage.

If it’s not in the local storage, it will be downloaded. If the hash of the file in local storage doesn’t match the one in the registry, will download a new copy of the file. This is considered a sign that the file was updated in the remote storage. If the hash of the downloaded file still doesn’t match the one in the registry, will raise an exception to warn of possible file corruption.

Parameters:

fname : str

The file name (relative to the base_url of the remote data storage) to fetch from the local storage.

Returns:

full_path : str

The absolute path (including the file name) of the file in the local storage.
