Can't run cell, cell execution errors out with 'Canceled' notification

Expected behaviour

When opening this notebook: OCTImagePrediction Notebook I expect the cells to run as they had in the past as seen as the committed output in the repo.

Actual behaviour

Instead when I try to run cells with MagicPython set as the kernel and Python 3.9.0 set as the interpreter, the kernel doesn’t properly connect and I see a notification with just the word Canceled. Not sure what the exact error is.

Steps to reproduce:

[NOTE: Self-contained, minimal reproducing code samples are extremely helpful and will expedite addressing your issue]

1. Clone OCTImagePrediction
2. Open Notebook.ipynb
3. Set Python 3.9.0 as the interpreter
4. Verify the kernel is set to MagicPython
5. Click run on the first code cell.
6. See notebook attempt to connect to kernel but then errors out with Canceled

@tanhakabir Sorry about the time this cost you. We actually did intend to have this, but there is currently (in some scenarios) a bug that prevented this from running in the new Code-Insiders interface. I believe that we have the resolution for this coming in our next release. Didn’t realize from the error message that you were hitting this scenario.

We believe this has been addressed in the most recent builds
