Hanging on ipywidgets cell

[rohanjha123]

Describe the bug
Otter assign hangs whenever it hits a cell using an interactive widget from ipywidgets and the command doesn't finish executing.

To Reproduce
Create a Python notebook with some otter tests along with the following code and try otter assigning it:

# ASSIGNMENT CONFIG
name: test
requirements: ../../requirements.txt
overwrite_requirements: true
template_pdf: false
solutions_pdf: true
generate:
    seed: 42
    show_stdout: true
python_version: 3.11

def say_my_name(name):
    """
    Print the current widget value in short sentence
    """
    print(f'My name is {name}')
     
interact(say_my_name, name=["James", "Bond", "James Bond"]);

More detailed notebooks with this issue have also been sent to Chris Pyles privately for security reasons.

Expected behavior
I expect the notebook to otter assign perfectly.

Versions
Python 3.11.0, Otter 5.1.3, more info here

Additional context
This was an issue on the data100.datahub but not on Chris' local machine.

@rohanjha123 I think this may be an underlying issue in nbconvert: jupyter/nbconvert#1921

[chrispyles]

As a temporary patch until that bug gets fixed, you can downgrade to nbconvert==7.2.5 on the machine running otter assign.

Thanks Chris!

Closing this as it seems to be an issue with nbconvert and not otter.
