Failed to use mne libraries in runtime. Pyinstaller

[Ferney beltran velandia]

Hi everyone,

I am trying to make a .exe file from python code, which imports mne libraries for EEG data analyses. 

I can generate the .exe file using the command line "pyinstaller myScript.py" without problems. However, when I execute the program, the next error is shown:

FileNotFoundError: [WinError 3] The system cannot find the path specified: 'C:\...\\AppData\\Local\\Temp\\_MEI74962\\mne\\channels\\data\\montages'

It seems like the mne libraries were not found in the analysis step of PyInstaller. 

I've already tried to generate a hiddenimport hook using the command line "pyinstaller myScript.py --hidden-import mne" but it was not successful. 

This hook is not pre-installed with PyInstaller by default, that's why I tried to include that new hook (called hook-mne.py) in the command line: 

"pyinstaller --onefile myScript.py --additional-hooks-dir=." but still no success. 

The hook-mne.py file has just the following line: hiddenimports = ['mne']

The specifications of my environment are:

Windows-10-10.0.17763-SP0

Python 3.7.3

PyInstaller 3.4

I would appreciate every suggestion.

Thanks!
