### Steps to reproduce

You can run my script on Mac

### Issue submission checklist

- [x] I report the issue, it's not a question
- [x] I checked the problem with documentation, FAQ, open issues, forum.opencv.org, Stack Overflow, etc and have not found any solution
- [ ] I updated to the latest OpenCV version and the issue is still there
- [x] There is reproducer code and related data files (videos, images, onnx, etc)
