The same installation works using python 3.9, however fails using python 3.11

The issue is also happening with other Python versions.
Fixed it installing pyyaml==6.0.1

still happening for python 3.11
What is the plan to properly support 3.11?

[mircealam]

python 3.11 support is being added in #1029

[mircealam]

support for 3.11 was added. please verify if you still have the issue + reopen if that's the case
