[SOLVED] Jupyter Kernel Keeps On Dying

arnuld · 2021-03-01 14:40:03

I have uninstalled jupyterlab and then removed these directories:

.config
.cache
.ipython
.jupyter

And re-installed jupyterlab but I can't get rid of this error whenever I open a notebook (even an empty one). Error just goes like an infinite loop. Same story with jupyter notebook.

NOTE: I am running latest update (pacman -Syu)

which kernel is that?

arnuld · 2021-03-01 18:00:11

What exactly are you asking?

arojas · 2021-03-01 19:39:01

which jupyter kernel are you running

arnuld · 2021-03-02 01:37:48

[arnuld@arch64 ~]$ pacman -Q jupyter
jupyter 4.6.3-2

[arnuld@arch64 ~]$ pacman -Q jupyterlab
jupyterlab 3.0.9-2

[arnuld@arch64 ~]$ pacman -Q jupyter-notebook 
jupyter-notebook 6.2.0-1

[arnuld@arch64 ~]$ ipython --version
7.19.0

[arnuld@arch64 ~]$ python --version
Python 3.9.2

:SOLUTION:

It was all my fault. I created a new file named "random.py" which was conflicting with Python's random.py. So, I just renamed the file and everything is fine now. This was the reasin it was immedaitely dying without even executing any code because by default Python was trying to load its libraries. Solution was in the full error message and I did the mistake of not reading in its entirety. I have updated the original post with full error message.
