WebOct 5, 2024 · It depends. But you can run pip uninstall phonopy and pip uninstall phono3py several times. After running these, it is recommended to find installed phonopy and phono3py and just rm -r them if you could found them. If you use conda env, it is fairly easy and safe just by conda remove -n --all. http://helper.ipam.ucla.edu/publications/gss2014/gss2014_12180.pdf
