Hi Helmut, Thanks for your bug report, however 2 things:
1/ The issue really lives in python-taskflow, in its definition of StrEnum, which is a class that inherits from both Python strings and Python Enum. 2/ Do you really think I need *ALL* of your build log here? I really need only what was after the "Failures during discovery" thing... Next time, it's much better to *attach* your build log, and just copy/past the end of the log. FYI, I do have a fix for taskflow which should fix everything, which in fact consists of removing the bad calls that it shouldn't do. Cheers, Thomas Goirand (zigo)
