[Mne_analysis] Uninstall all the older versions of MNE and its dependencies

[Burkhard Maess]

Hi,

there is at least one way on how updating all packages with two pip
commands:

pip freeze >requirements.txt
# search and replace '==' with '>=' within the file requirements.txt
pip install -r requirements.txt --upgrade

this is taken from
https://www.activestate.com/resources/quick-reads/how-to-update-all-python-packages/

best,
Burkhard

Thus when I try to install newer MNE 0.21.0 using <<pip install mne>>, the older dependencies are not getting replaced by the latest versions of dependencies.  And I'm a bit skeptical, that the latest MNE might use the latest versions of the dependencies.
