MarsSeed [1] filed an orphan request for etmtk [2]: This package needs maintainer attention. Flagged out-of-date since 2022-05-28. The current version crashes with a TypeError exception. The last available release on PyPI is from 2019, not sure if it works with current Python 3.11 or not, but it can only be found out if someone adopts this tries out the updated version.
