Jupyter Error code

JupyterLab
1

Hi, new to this forum. I am having difficulty compile and executing code. I am using Pycharm with Jupyter notebook. The message I am getting is

JupyterRestClientErrorResponseException: Wrong response for Jupyter sever, code 500 message, ‘module’ object is not callable, trackback null

Can someone guide me to fix the problem?

You have given us very little to go on. Please read Getting good answers to your questions . I also really think the last reference on that page is especially good: How do I ask a good question?.

Was Jupyter ever working through Pycharm for you? Did print("Hello World") work if you are using an ipykernel? If not, what kernel?

Have you seen Jupyter Notebook does not run in PyCharm and explored various suggestions there or 500: Internal Server Error - #5 by larabrian ?

This is what get when in installed Jupyter.

[W 2025-09-16 15:51:33.220 ServerApp] Kernel Provisioning: The ‘local-provisioner’ is not found. This is likely due to the presence of multipl
e jupyter_client distributions and a previous distribution is being used as the source for entrypoints - which does not include ‘local-provisio
ner’. That distribution should be removed such that only the version-appropriate distribution remains (version >= 7). Until then, a ‘local-pr
ovisioner’ entrypoint will be automatically constructed and used.
The candidate distribution locations are: ['C:\Users\jlope

It seems to be saying you already had things installed and didn’t clean up before installing this latest time?

This comes about when I click green arrow to run code. Is there a way to clear everything and start new. I had tech people install and reinstall pycharm, but we have little knowledge of jupyter notebook.

Gee these computers are getting smarted than us. I asked ChatGPT to resolve the error, and it went ahead and recreated the notebooks and reconfigured everything. Now it is working. Here is the executable it told me use. Thanks everyone. It is just scary and exciting to get advice from ChatGPT. Insane!

for future reference. I could not inset the zip files but notes list what should be said to ChatGPT

Inside the ZIP

  • setup_jupyter_fix.ps1 → PowerShell script that creates/repairs a clean .venv and installs pinned, compatible Jupyter packages.

  • run_setup_jupyter_fix.cmd → Double-click launcher for Windows (calls the PowerShell script with ExecutionPolicy bypass).

  • README_JupyterFixer.md → Easy-to-read instructions covering:

    • How to run the toolkit

    • Steps to update PyCharm after setup

    • Optional flags (-ForceRecreate, -PyExe)

    • Notes on which errors this fixes

How you’ll use it later

  1. Drop the files in any new project folder.

  2. Double-click run_setup_jupyter_fix.cmd.

  3. When it finishes, update PyCharm to use the new .venv.

  4. Test by running:

    .\.venv\Scripts\python.exe -m jupyter lab --debug

Glad you have it sorted out now.
Hopefully what has been provided gave enough details that others can follow along if they encounter this situation.

It mainly looked like installing properly using a .venv with compatible packages and then assign PyCharm to use that, I think.
