Steps to reproduce:

[NOTE: Self-contained, minimal reproducing code samples are extremely helpful and will expedite addressing your issue]

  1. That's my one repository linked with github. I am able to run Notebook from other folder or directory but getting error when running notebook from this repository. I cloned the same repository to another directory and issue remains.

Thanks for the bug.

It looks to me like the kernel can't be run by jupyter. If you attempt starting jupyter using the same kernel outside of VS code it might give you more information as to why. To do so you'd:

  1. Go to the directory with the problem in terminal
  2. Run jupyter notebook
  3. Create a new notebook
  4. Pick the python38264bit58e42c9575d24eb58f427896571571af kernel
  5. Look at the output at the terminal (assuming it will fail too)

Additionally if you could set this setting: image

That should show a lot more output in the 'jupyter' output tab in VS code.

Thank You. I also ran the notebook from terminal and web browser. It also failed to connect the kernel. I was curious to know the reason for this.

rchiodo commented 3 years ago

I was curious to know the reason for this.

It should list the reason in the terminal. You can get more info from jupyter by setting the log level higher:

jupyter notebook --log-level=DEBUG

That sounds like the kernelspec might be invalid. At least stack overflow is pointing to unicode problems that might cause that subprocess error.

Can you try deleting this kernel directory (it was created by VS code) /home/ubuntu/.local/share/jupyter/kernels/python38264bit58e42c9575d24eb58f427896571571af

And then trying again?

I deleted that Kernel. I had to set a new kernel after opening jupyter notebook. I am sharing both my terminal and browser issue.

rchiodo commented 3 years ago

Did you start and stop jupyter after deleting that kernel?

That looks like it's trying to attach to the existing kernel.

Yes. I restarted the kernel. It showed like "Start without kernel" or "Set up a new kernel" Then I set up a new kernel.

rchiodo commented 3 years ago

Sorry I meant kill jupyter itself. Not just the old kernel. Restart jupyter notebook

Sorry. I meant that. After deleting, I restarted the Jupyter from Terminal

rchiodo commented 3 years ago

And what does the terminal output show? Does it give you a 404 error?

This issue here may be relevant. https://github.com/jupyter/notebook/issues/5814

Hopefully if you're getting an error from jupyter it's giving you something more than just a 404.

Hopefully if you're getting an error from jupyter it's giving you something more than just a 404.

I am facing this issue from yesterday. Even if I clone the same repository from my github, it throws same problem. So, what could be the notebook's internal issue? Also, I noticed that, I am facing the same problem for each notebook in that directory even after creating new notebook. My settings.json is 

{
    "files.associations": {
        "deque": "cpp",
        "string": "cpp",
        "vector": "cpp"
    },
    "python.pythonPath": "/usr/bin/python3"
}

And another notebook is running well, that has only on different directory


{
    "python.pythonPath": "/usr/bin/python3"
}
fkhjoy commented 3 years ago

So, I found a solution. If I run from different window of vscode and not being in the directory of the notebook, it runs smoothly.

So, Kernel is failing when I run being at the same directory in a window. And the problem is in the directory for all .ipynb and also .py file I recently noticed.
