The last step didn’t work for me.
git clone GitHub - fermisurfaces/IFermi: Fermi surface generation, analysis and visualisation.
cd IFermi
pip install .[tests]
zsh: no matches found: .[tests]
is the .[tests] still supposed to work?
The problem is zsh. You need to backslash the . Possibly the brackets too, but the back of my mind doesn’t remember that being an issue. It should be pip install \.[tests] in zsh.
