It in fact works, I successfully installed it and also ran one of the example files. (I did change zsh back to bash originally because I just couldn't get anything done...) Thank you very much!

Further comments: initially I had error messages related to Numpy. Within the openmps environment I uninstalled and reinstalled Numpy through pip, and then I got an error message about not having Scipy. I installed Scipy through pip and that one was alright as well, then I received the error message outlined above. Not sure if it's relevant at all but I don't understand these technicalities very much, I just want to get some phase diagrams of topological insulators. Thank you for anyone's help in...
