Python 3.10.11 macOS: tk.h version (8.5) doesn't match libtk.a version (8.6)

[QuLogic]

Description:
Azure appears to be slowly rolling out image version 20230408.1. This seems to have hit our Python 3.10 jobs with the error:

RuntimeError: tk.h version (8.5) doesn't match libtk.a version (8.6)

This didn't affect the 3.9 job, which is also using the 20230408.1 image.

Action version:
0.214.0

Platform:

• Ubuntu
• macOS
• Windows

Runner type:

• Hosted
• Self-hosted

Tools version:
3.10.11

Repro steps:

Expected behavior:
Tk works correctly.

Actual behavior:
A runtime error is raised when attempting to import Tk:

RuntimeError: tk.h version (8.5) doesn't match libtk.a version (8.6)

This is a similar issue to #402.

Just an FYI I'm encountering the same issue with my rfswarm builds, the issue seems to be specific to python 3.10 on MacOS

Not sure how helpful this is but I'll add it in case it helps find the cause:

OS	Python Ver	Test Result
ubuntu-latest	3.7	Pass
ubuntu-latest	3.8	Pass
ubuntu-latest	3.9	Pass
ubuntu-latest	3.10	Pass
ubuntu-latest	3.11	Pass
macos-latest	3.7	Pass
macos-latest	3.8	Pass
macos-latest	3.9	Pass
macos-latest	3.10	Fail
macos-latest	3.11	Pass
windows-latest	3.7	Pass
windows-latest	3.8	Pass
windows-latest	3.9	Pass
windows-latest	3.10	Pass
windows-latest	3.11	Pass

Here's my stack trace from stderr:

Traceback (most recent call last):
  File "/Users/runner/work/rfswarm/rfswarm/rfswarm_manager/rfswarm.py", line 6954, in <module>
    core = RFSwarmCore()

    raise RuntimeError("tk.h version (%s) doesn't match libtk.a version (%s)"
RuntimeError: tk.h version (8.5) doesn't match libtk.a version (8.6)

A quick internet search for "RuntimeError: tk.h version (8.5) doesn't match libtk.a version (8.6)" brought me here.

Let me know if I can be of any more help?

Dave.

I'm seeing this also, Python 3.10 on macOS failing with a tk.h related error. I feel I've had this same thing a few years ago, maybe #402 mentioned above...

My last good build was 29 March, and the configuration was:

platform darwin -- Python 3.10.10, pytest-7.2.2, pluggy-1.0.0, matplotlib-3.7.1-cp310-cp310-macosx_10_12_x86_64.whl

Currently the configuration is:

platform darwin -- Python 3.10.11, pytest-7.3.1, pluggy-1.0.0, matplotlib-3.7.1-cp310-cp310-macosx_10_12_x86_64.whl

Some change to Python version, no change to Matplotlib.

And now it's spread to Python 3.9: https://dev.azure.com/matplotlib/matplotlib/_build/results?buildId=34189&view=logs&j=d565cd3d-5b64-5d92-00ca-77c8c01737e7&t=44ca2d65-e117-5342-7366-f7ed442af407&l=416

Is there any progress? It's been 2 months now.

It also seems to be affecting github actions: https://github.com/matplotlib/matplotlib/actions/runs/5326817190/jobs/9649372136?pr=26154#step:13:420
