Hey there

The setup for getting the error can be very basic:
-Start a runtime (e.g. 17.3 LTS ML with an Standard_NV36ads_A10_v5 [A10] 440 GB memory, 1GPU)

- In a notebook, install the cv2 package like this:

This seems to install correctly

- Then try 

This gives the error:

Fatal error: The Python kernel is unresponsive.

The details of the error are:

Fatal error: The Python kernel is unresponsive.

Strangely enough, this setup was working fine a few weeks ago.
If anyone has the same issue or knows a workaround, I would be delighted to learn about it.

Best,
