Conflict with OpenCV

[doit-ceo]

I followed your instruction to get Mac M1 working and it worked perfectly, thanks a lot

But adding openCV to the environment breaks Jupiter (local device)

I can start Jupiter, it but I can't connect to the kernel anymore !

Currently OpenCV is not a required component for this course, so it is really out of scope for what I am providing here.

I do know that there are some complexities to installing OpenCV on M1, this might be of help. https://opencv.org/opencv-python-for-apples-m1-chip-a-detective-story-with-a-happy-ending/

@jeffheaton I found that installing TF from here (https://www.youtube.com/watch?v=ykCY_tJbhNw) gave me better results as it truly utilize M1 / ML chip, following your tutorial result in GPU utilization (good) but the youtube above added support for ML and I managed to run your notebook with no CPU or GPU activities, also it was compatible with openCV
