Jupyterlab requirement

[RobVor]

Hi all,

This seems to be related to the PR https://github.com/plotly/plotly.py/pull/5104

The check for jupyterlab is still failing on my end. I have a LabEnv that uses other kernels in other environments. It keeps prod environments lean.

Similar to the original poster of the issue linked to the above PR, I get the following error when trying to plot using plotly.

AttributeError: 'NoneType' object has no attribute 'version'

plotly version:

import plotly
plotly.__version__
'6.0.1'

Python version:

from platform import python_version
python_version()
'3.12.10'

Jupyterlab/host version:

jupyter lab --version 
4.4.1

Jupyterlab/client version:

import jupyter_client
jupyter_client.__version__
'8.6.3'

BTW, the check above for the jupyter_client is probably what needs to be added in the code to fix remote execution. Below is how I 'fixed' it so I can move on for the time being, but probably missing other nuances.

    elif "jupyter-lab" in parent_process:
        jupyter_lab = optional_imports.get_module("jupyterlab") or optional_imports.get_module("jupyter_client")
        if jupyter_lab.__version__ < "3":

You're also getting Mime type rendering requires nbformat>=4.2.0 but it is not installed, which is what https://github.com/plotly/plotly.py/issues/4512 is about.
