If None, the environment variable or config parameter
MNE_DATASETS_ERP_CORE_PATH is used. If it doesn’t exist, the

is not found under the given path, the data
will be automatically downloaded to the specified folder.
Force update of the erp_core dataset even if a local copy exists. Default is False.
If True (default), set the
MNE_DATASETS_ERP_CORE_PATH in mne-python
config to the given path. If None, the user is prompted.
