External Email - Use Caution

Hello,
I am trying to run a script based on the example in method data_path from
mne.datasets.eegbci:

import os
from mne.datasets import eegbci

url = 'Index of /static/published-projects/eegmmidb/1.0.0/’
eegbci.data_path(url, os.getenv('HOME') + '/datasets')

and get the following error:
...
File
"/home/user/venv/torch/lib/python3.7/site-packages/mne/utils/fetching.py",
line 173, in _fetch_file
    shutil.move(temp_file_name, file_name)
  File "/home/user/venv/torch/lib/python3.7/shutil.py", line 564, in move
    raise Error("Destination path '%s' already exists" % real_dst)
shutil.Error: Destination path
'/home/user/datasets/MNE-eegbci-data/files/eegmmidb/1.0.0/.part' already
exists

I clarify that the folder did not previously exist.
What could be the problem?

Best regards,

Hello!

Did you try eegbci.load_data instead of eegbci.data_path (according to the docs https://mne.tools/dev/generated/mne.datasets.eegbci.load_data.html#mne.datasets.eegbci.load_data)? What do you want to do in the first place?

Yes, that way
<mne.datasets.eegbci.load_data — MNE 1.7.0.dev17+g20174f448 documentation;
it works. But theoretically the other script should also work based on
the description
of the function
<https://github.com/mne-tools/mne-python/blob/22dfbb5c55f09b88f595dd5c6d83dac71335df97/mne/datasets/eegbci/eegbci.py#L46&gt;\.
I do not understand what is wrong.

The error is complaining about a `.part` file (i.e., partial download). Did you abort downloading on an earlier attempt, before you got this error? Does it work if you delete the `.part` file and try again?

Yes, is true. The problem was in the path, it is necessary the full path as
argument, for example:

url = 'https://physionet.org/files/eegmmidb/1.0.0/S001/S001R06.edf’

Thanks.
