To my knowledge, we do not currently have a required version; the current state is it either works or it doesn’t, and if it doesn’t it’s on you to figure that out from the failures.

I’m not opposed to adding one – if there’s interest. I’d have to think about the best place to add it. The idea of making it its own test is interesting. It wouldn’t prevent you from getting other test data, but it would let you know you aren’t on the ideal version and there may be unpredictable results. Ponder ponder…

Andrew,

Not a scheme that I would consider a “good” scheme. You can see what we’re running CI against (in Mu and EDK, both), by checking for the  “UsePythonVersion” command in the .azurepipelines/pr-gate-steps.yml file.

Bret,

If I understand correctly the CI list is the recommended versions, but not the required versions. Do we have any concept of the required versions? I guess we could put a python assert to enforce min Python version? I guess we could be more aggressive on the required Python version (forces people to install a custom Python version for the edk2 build), or build a CI test that tests the min Python version for the tools...

Sorry mostly thinking out loud…. 

Thanks,

Andrew Fish

Shivanshi,

I just ran a build on my system with that exact version of Python (3.9.0). Did your build produce a “BUILD_TOOLS_REPORT.json” file? If so, can you send it?

Can you also send the exact command that you’re running when you see this issue?

Thanks!

It looks like a Python 3.8.x vs 3.9.x issue.

Do we have a scheme to require a min Python version?

Thanks,

It looks as if you’re using Mu Q35 as your platform. Can you tell me what branch you’re on?
