arviz_base.get_data_home

arviz_base.get_data_home(data_home=None)

Return the path of the arviz data dir.

This folder is used by some dataset loaders to avoid downloading the data several times.

By default the data dir is set to a folder named ‘arviz_data’ in the user home folder.

Alternatively, it can be set by the ARVIZ_DATA environment variable or programmatically by giving an explicit folder path. The ‘~’ symbol is expanded to the user home folder.

If the folder does not already exist, it is automatically created.

Parameters:

data_homestr, optional

The path to arviz data dir.
