Kernel crashes when creating a matplotlib plot

[aldojacopovirno]

Applies To

• Notebooks (.ipynb files)
• Interactive Window and/or Cell Scripts (.py files with #%% markers)

What happened?

Error:
The Python 3.10.0 kernel in Jupyter Notebook continues to crash locally on my system. I have tried several solutions, including kernel restarts, code checks, and using a new virtual environment, but the issue persists. The detailed error message is as follows:

The kernel 'Python 3.10.0' died while executing code. Please check the kernel logs for more details.

Steps Tried:

1. Restarting the Jupyter kernel.
2. Checking Python code for syntax or logic errors.
3. Creating and using a new Python virtual environment.
4. Monitoring system resources to ensure there is sufficient available memory.
5. Updating Jupyter and related extensions.

Additional Details:

• The issue appears to be specific to my local environment, as the notebook runs correctly on other systems.
• I have reviewed detailed kernel logs but have not found additional information to help resolve the issue.

Thank you for your assistance in resolving this problem.

Local

[DonJayamanne]

Sorry for not getting back to you on this issue.

The issue appears to be specific to my local environment, as the notebook runs correctly on other systems.

This seems to be an issue with kernel dying due to external issues.
E.g. the code causes the kernel to crash instead of VS Code.
E.g. are you certain you are running the same notebook in the exact same Python environment. Its likely you aren't

VS Code doesn't really causes crashes, its the Python code that is running in the kernel thats causing the kernel to crash and thats actually beyond the control of VS Code.

Pelase can you try running the same notebook outside VS Code against the exact same Python environment and try again.

This problem must arise.
Reproduce steps
Run ipynb within WSL
Run code within a cell.
The code has output and image output

import matplotlib.pyplot as plt
print and plt show

There are two questions now.
If there is no scheduled deletion of logs.
So when the output reaches 1000 lines, an error will be reported and the kernel will stop
The error willingness exceeds the maximum supported number of rows. Therefore, files are required. But the file address is illegal，because use wsl. Causing kernel errors here. And stop
So the function of scheduled deletion of logs was added.
So there was this mistake
This error occurs when logs and images are generated while deleting

I'm sorry however I am struggling to understand the problem now.
there's more information leads to me getting confused.

What do you mean by this?

Can you try the following:

• Create a new workspace folder
• Create a new Python file
• Run one cell with the following code

import matplotlib.pyplot as plt
plt.figure()
plt.plot([1,2], [1,2])
plt.show()

Does this work?

Given the fact taht you have mentioend about logs, scheduled deletion, eetc, I'm inclined to believe that this is caused by some code at your end.

Also, does this issue repro, when you use Jupyter Lab?

[xiezhipeng-git]

@DonJayamanne
This is no problem. The problem is related to exceeding the maximum length and generating and deleting simultaneously.
Unfortunately, however. I am currently unable to access WSL.
Because of this issue microsoft/WSL#11849
I can't enter WSL at all now. I don't know if the files can be recovered.
The problem needs to be divided into two parts

1. I didn't express myself clearly. Because I forgot to use Windows VSCode and WSL VSCode for the files in WSL, the result may be different.
   Specifically, problem one is opening the windows VSCode project in the WSL file path. Then any printed statements. If it exceeds 1000 lines (or possibly 5000 lines, I can't remember which one), an error will be reported. Then the Jupyter kernel terminates. There will be an error indicating that the file cannot be created. From the error message, it appears that this path is unique to Windows using WSI files. But when the file exceeds the maximum length of the Judge kernel, a file needs to be generated. But the generated failed in here.
   So, in order to solve this error, I introduced dynamic deletion of logs.

from IPython.display import clear_output
clear_output(wait=True)

2. This method solves the above-mentioned errors that can cause kernel errors and prevent the program from continuing to run.
   But when I continue add plt related drawing code inside the output(hase the clear_ouput code,and more 5000 lines). The error mentioned in this article occurred
   If I only draw once, then the print statement will still be repeated many times. Because it will be cleared. After exceeding 5000 lines, there is no problem. Otherwise, if I print and draw together. This error occurs when there are a lot of printing times

[DonJayamanne]

Thanks, but Still struggling to understand the issue , please can you share a very simple notebook with a simple plot like the one I shared that can be used to replicate this issue

Also can you share screenshots of the error messages, it’s difficult to tell what the problem is without those details

[xiezhipeng-git]

import matplotlib.pyplot as plt
from IPython.display import clear_output
for i in range(6000):
    #question 1 wsl path windows vscode project only print no clear_output and plt show Kernel crash
    print(i)
    clear_output(wait=True)
    # or try false
    #clear_output(wait=False)
    plt.figure()
    plt.plot([1,2], [1,2])
    plt.show()

@DonJayamanne
Now I can not run in wsl.because my wsl is broken.
but these code could cause vscode to crash or jupter Kernel crash in only windows project. You can try in wsl file path windows vscode project and wsl path wsl vscode project.

Can you try laucnhing Jupyter Lab inside the same WSL enviorhnment from the same Python env d:\my\env\python3.10.10\python.exe
Run the same code there as well, and see what happens
When launching Jupyter Lab in WSL, plese ensure to pass --debug argument so we can see whats going on,
This way when it crashes in JupyterLab as well, we'll have the logs in the terminal.

[DonJayamanne]

I've tried this at my end , and it works as expected, took a while to run the cell, but it ran completely without any errors.

[xiezhipeng-git]

@DonJayamanne
Can't we see the problem through the Windows logs I provided?
I cannot use WSL now because it is damaged and I don't know when it will be restored.
Because I have this issue with both Windows and WSL. Can you provide me with a complete command that can be implemented through Windows

Today, I discovered that the Juypter plugin has automatically updated
And now I can't reproduce the problem on Windows either. WSL is currently unclear

Try opening the file project using Windows VSCode in the WSL path. Then only print. Not cleared. Can you reproduce the path error issue?

After trying again, it was reproduced.

How does switch to Jupyter lab? And, although I get the same error as @https://github.com/aldojacopovirno. But it's not necessarily the same error, yet the link you gave for the introduction is just the current page.Are you sure you didn't give the wrong one?

[DonJayamanne]

The link was correct, basically please use Jupyter lab from the same environment
‘d:\my\env\python3.10.10\python.exe -m pip install jupyterlab’
Then run Jupyter from that same environment
‘ d:\my\env\python3.10.10\python.exe -m Jupyter lab’

Note, please ensure you have activated the python env as well

warn] Failed to get activated env vars for d:\my\env\python3.10.10\python.exe in 58ms

Btw, what kind of environment is this? Conda or virtual environment or other?

@DonJayamanne
The term 'jupyter' is not recognized as a name of a cmdlet, function, script file, or executable program.
Check the spelling of the name, or if a path was included, verify that the path is correct and try again.
only
PS D:\my\work\test\python_test> jupyter-lab --version
4.2.1
windows,vscode,Nomal python. No use virtual environment
If use jupyter-lab
There is no Kernel crash problem.
So the problem is from vscode or ipykernel?

[DonJayamanne]

Please install Jupyter into the same Python environment using the following script

‘d:\my\env\python3.10.10\python.exe -m pip install jupyterlab’

@DonJayamanne
Your local version is outdated.
The new version seems to be like this here.
There is only a unified Jupyter-feature name. Similar commands like this

[DonJayamanne]

Can you share a screenshot of the output from the terminal when you run here above command

[xiezhipeng-git]

Is it Jupyter-lab?

There is no crash if use Jupyter-lab
The crash state only in vscode

[DonJayamanne]

Please can you confirm you ran this command

‘d:\my\env\python3.10.10\python.exe -m pip install jupyterlab’

I’m sorry, but can you try the above first,
We need to ensure Jupyter lab is installed in the same Python environment

use d:\my\env\python3.10.10\python.exe -m pip install jupyterlab
and
jupyter-lab
It is crashed

[DonJayamanne]

Than you for getting back with that information

This proves that the problem is not with vscode
The kernel is crashing in Jupyter lab as well, as it’s not related to vscode I’m closing this issue

I would suggest recreating the python environment, or using another environment and reinstalling the packages

@DonJayamanne
So where should this issue be fed back to? PLT or Jupyter
