[Mne_analysis] Assertion error when running mne.io.read_raw_brainvision

[Alexandre Gramfort]

hi,

as explained on the readme [1] you need to do:

"
for the latest development version (the most up to date):

pip install -e git+https://github.com/mne-tools/mne-python#egg=mne-dev --user
"

in a terminal.


Do not type it in the python interpreter of pycharm but in a console/terminal.
