Jupyter notebook not able to run on Conda environments

[sravanpannala]

Issue Type: Bug

I installed Ipykernel and jupyter packages in a Conda environment. I then selected that environment as Kernel. I tried to run a simple code in a cell

x = 5
y = 4
x+y 

The kernel does load and I get this error:

Kernel died with exit code 1. C:\Users\spannala\AppData\Roaming\Python\Python39\site-packages\traitlets\traitlets.py:2196: FutureWarning: Supporting extra quotes around Unicode is deprecated in traitlets 5.0. Use 'hmac-sha256' instead of '"hmac-sha256"' – or use CUnicode.

The same error is occurring with poetry virtual environments This is now fixed after totally removing Conda from the system. It seems the problem lies in conda itself.

@sravanpannala Have you tried following some of the fixes mentioned on this issue? mhammond/pywin32#1431

[sravanpannala]

@claudiaregio I will take a look, but the issue here is I'm trying to use conda but VS Code is trying to load win32api from the base python. Using base python works in Jupyter notebooks, also using other virtual environments. I'm not very good at diagnosing errors so I don't understand what is going on here.

[sravanpannala]

I figured out the problem. Miniconda's base python is 3.9.1, but creating a new env resulted in installing python 3.9.5. I think this is causing the problem in ipython-kernel. Restricting the python version to 3.8 while creating a new env solved the issue.

@sravanpannala great! Glad you were able to get that fixed :) Closing as resolved
