First Cell having trouble

[lkorczowski]

@RobinGuillard reported an error in the notebook https://github.com/lkorczowski/Tinnitus-n-Sleep/blob/master/Notebooks/Bruxism_detection.ipynb

He couldn't load the Config notebook.

Please provide error log.

Here is the error log I got when executing the first "imports" cell of the noteebook:

ModuleNotFoundError                       Traceback (most recent call last)
<ipython-input-196-0b857fcdc193> in <module>
      6 import scipy
      7 import seaborn as sns
----> 8 from tinnsleep.config import Config  # please add your data path in the module
      9 from tinnsleep.data import CreateRaw, RawToEpochs_sliding
     10 print("Config loaded")

ModuleNotFoundError: No module named 'tinnsleep'

[lkorczowski]

this error comes when tinnsleep is not in python path, which is important. Usually, you want that you environnement to have the git folder in the python path

You can use absolute path

import sys
sys.path.append('/path/to/main/git')

or relative path use ('..') > one folder up from notebooks/ folder

[lkorczowski]

Without having in sys path, you can't do anything ^^

At last I could load the tinnsleep modules!! But directly after, when I try to run the second cell, I get:

ValueError: No EEG channels found.

From my point of view, it is because you suppressed the "montage" option when you call the CreateRaw function...

[lkorczowski]

What version of mne do you have ?

I have 20.0 and not problem

This raise ValueError is not anymore in _set_montage: https://github.com/mne-tools/mne-python/blob/1639ab47dd41a73e9e95962e766c80c102cc70f1/mne/channels/montage.py#L658-L762

I think that issue has been managed by :

• adding PATH
• have a correct environment with up-to-date mne
