Hello Patrice, Thanks for the report.I checked with upstream and we are wondering, what is the actual version of your default python3 interpreter ? (python3 --version)
We cannot reproduce the error you described, neither on my system nor on upstream's author ones. It seems this could be because the python3 interpreter that you are using is older than 3.7 (that's why I asked for the version above).
