  The virtmat_kernel requires python 3.8 or later. On bwUniCluster the version 3.8.6_gnu_10.2 does not allow to upgrade pip from 20.2.1 to 22.3.1. Aafter a successful upgrade command I find with python -m pip --version that it is still the old version. The new pip version is necessary because otherwise I get

  (python-3.8.6_gnu_10.2) [jk7683@uc2n994 vre-language]$ python -m pip install -e .
  ERROR: File "setup.py" not found. Directory cannot be installed in editable mode: /pfs/data5/home/kit/scc/jk7683/vre-language
  (A "pyproject.toml" file was found, but editable mode currently requires a setup.py based build.)

  that seems to be a bug in pip 20.2.1.
