[BUG]: example max/examples/inference/yolo-python-onnx fails under WSL

[bmerkle]

Bug description

I ran MAX examples under WSL. Everything works fine, except examples max/examples/inference/yolo-python-onnx
Note that my WSL currently does not have a video cam, so the example falls back to use the video file. (see also #259)
However this seems not to work 100%. error message:

Steps to reproduce

• Include relevant code snippet or link to code that did not work as expected.
  start the example:
  (YOLO Python Onnx) merklbe1@DEAGM13714:~/max/examples/inference/yolo-python-onnx$ bash run.sh

• If applicable, add screenshots to help explain the problem.
  Please see the errormsgs

• Include anything else that might help us debug the issue.
  Note that my WSL currently does not have a video cam, so the example falls back to use the video file. (see also [Feature Request] add tips to run e.g. yolo sample under WSL (video cam) #259)

Thanks! this is a bit hard to reproduce due to lack of access to windows machine.

Thanks, i understand.
If you send me a hint/instruction how i can debug this, i can search the root cause or send log files.
I tried with -v or --verbose but this does not enable logging, and i did not found documentation about enable debug/logging
