What happened?

Hi Folks,
Whenever I run my .ipynb, the kernel is interrupted at the cell 31. I've tried with many search such as:

uninstall & reinstall 
    ipykernel
    ipython
    jupyter_client
    jupyter_core
    traitlets
    ipython_genutils

conda install ipykernel --update-deps --force-reinstall
python -m pip install traitlets==4.3.3 --force-reinstall
python -m pip install pyzmq==19.0.2 --force-reinstall

...from the following sources: stackoverflow, github, github
But still no hope. I got the same issue with VSCode Jupyter notebook on pure Win10.

Any help please!?
With thanks - BK

@BinhKieu82
Thanks for filing this issue,

• Whenever I run my .ipynb, the kernel is interrupted at the cell 31. I've tried with many search such as:

  • Please could you send a copy of the notebook.
• Does this issue repro, when you run any other notebook with a simple cell such as print("hello World")
  • Its possible you are using some package thats gettig called in the 3rd cell thats causing the kernel to die.
• Does this issue repro outside VS Code, when using Jupyter Notebook?
• Please install the Pre-release version of the extension (this contains all of the latest fixes)
  • We'll be releasing a new version of the exension in a few days (with the pre-release you don't have to wait)
• Please could you enable logging as follows:
  • Open settings & go into Jupyter->Logging
  • Change the value to verbose
  • Reload VS Code,
  • Attempt to repro the issue & then copy the output from the Jupyter output panel.

Please provide the complete output from the Jupyter output panel, not just the error, I'll nee to see what's going on before things fall over and what was executed.

Hi @DonJayamanne ,
Here are the files as requested

Please could you enable logging as follows:

wsl_vscode_jupyter_log.txt

Please could you send a copy of the notebook.

14_creating_synthetics.zip

Does this issue repro, when you run any other notebook with a simple cell such as print("hello World")

No, I can run other notebook smoothly

Its possible you are using some package thats getting called in the 3rd cell thats causing the kernel to die.

I'm not sure about this

Please install the Pre-release version of the extension (this contains all of the latest fixes)
We'll be releasing a new version of the exension in a few days (with the pre-release you don't have to wait)

You meant jupyter-notebook extension on VScode? I will try it soonest

Anything that you need, just let me know.
Thank you - BK

• Can you try to run this same notebook in classic Jupyter Notebook against the same python environment.
  Please install Jupyter into /home/bruce/anaconda3/envs/devito & run it using python -m jupyter notebook and try running your notebook, looks like there are problems with the package.
  Let me know if this works or not (i.e. whether this works outside VS Code, in classic Jupyter Notebook against the same Conda Environment).

• Please could you provide the environment yml file
  Activate the devito environment in the terminal using conda activate devito
  Then run the command conda env export > environment.yml and upload the environment.yml file here.

• Also, please note there are errors in the output, evidence of the fact that the packakge doesn't work or needs to be re-installed.
  Please consider re-installing this package

qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found.
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

Available platform plugins are: eglfs, linuxfb, minimal, minimalegl, offscreen, vnc, wayland-egl, wayland, wayland-xcomposite-egl, wayland-xcomposite-glx, webgl, xcb.

Fatal Python error: Aborted

I tried running jupyter on my Chrome browser on the same conda env, it also stopped at the same cell. Below is the yaml file.
environment-dev.zip
Let me try recreate the env. What i'm scare is, as you pointed out, the conflict among libs. If it is true, then how can i overcome that

[DonJayamanne]

stopped at the same cell

looks like this isn't an issue with vascode itself,as you get the same problems outside vscode.

how can i overcome that

id suggest stack overflow or the repo specific to the package you are using.

thanks for the information provided, closing as this isn't an issue caused by vscode

[BinhKieu82]

Thanks @DonJayamanne, at least we can conclude that the IDE is innocent :). Let's close this issue

[DonJayamanne]

@BinhKieu82 have you managed to resolve this issue?
Btw, I checked your yml file, it didn't contain everything, it was pointing to a requirements.txt file which wasn't in the zip file.

Hey guys! i'm having the same issue.
And my setup is basically identic to the Binh's one.
Im using the latest tensorflow version (2.8) and the latests CUDA and cudNN (my GPU: NVIDIA GTX 1060). Python Kernel's version is 3.10.4
Curently i'm developing GANS to draw faces....but due to this kernel issue i'm trying with a simple MNIST based NN and when i reach the point of training the network my Kernel just die.
This is my VScode log:

Error: Canceled future for execute_request message before replies were done

Also: the same code run on my girlfriend's Jupyter Notebook, but not on mine. Then i tryed to force TF to work just with the CPU, i was able to do that using this code:

import os
import tensorflow as tf

os.environ['CUDA_VISIBLE_DEVICES'] = '-1'

if tf.test.gpu_device_name():
print('GPU found')
else:
print("No GPU found")

#No GPU found

And it works! so the problem occour when i try to use TF-gpu....problem is that i dont know how to fix this. My PATH variables are set just fine. I really dont know where to start.
P.S. sorry if my english is bad.
