In my experience the only working solution was pip in virtualenv, for
example in my lab we use a lot Spacepy package which isn't in anaconda
repos.
Then our install workflow is pretty easy:
sudo dnf install python3-virtualenv
mkdir ~/P3Venv
virtualenv-3.X --system-site-packages ~/P3Venv
source ~/P3Venv/bin/activate
pip install --upgarde jupyter matplotlib pandas spacepy numpy ...
Then we add few aliases on our bashrc to get quick access to jupyter-
notebook and activate venv.
The main pitfall here is that we need gcc and some devel packages, here
"dnf provides" is a friend.
