Kernels in kernel picker have the same name and do not use "display_name" field of kernelspec

[saisasidhar]

Environment data

• VS Code version: 1.62.3
• Jupyter Extension version (available under the Extensions sidebar): v2021.10.1101450599
• Python Extension version (available under the Extensions sidebar): v2021.11.1422169775
• OS (Windows | Mac | Linux distro) and version: Windows 10
• Python and/or Anaconda version: Python 3.7
• Type of virtual environment used (N/A | venv | virtualenv | conda | ...): poetry
• Jupyter server running: Remote

Expected behaviour

Name of the kernel as specified in display_name field of a kernelspec's kernel.json should be shown in the kernel picker of "Jupyter Interactive Window". I think it was displayed properly in 2021.8.11 when I reported #7063

Actual behaviour

All kernels in the kernel picker have the same name such as poetryprojectname-XYZ-py3.7 (Python 3.7.12) ~/.cache/pypoetry/virtualenv....

Steps to reproduce:

1. Create a venv using virtualenvironment or any package manager like poetry
2. Install jupyter pip package in the above env
3. Change directory to $VIRTUAL_ENV/share/jupyter/kernels
4. Duplicate python3 directory to new directory, say new_kernel
5. Change display_name field in new_kernel/kernel.json
6. Restart vscode and open the kernel picker, it should now display two kernels for the env, but both bear the same name

Logs

Haven't found anything relevant in the logs

Thanks for the bug. This is likely because the cache hasn't updated.

The output log should show what we found while searching for kernels. Can you include it here?

[rchiodo]

Sorry you have to turn on 'verbose' logging:

For me, this is by design because the second kernelspec (even though it has a custom name) is really the same as the 'python3' kernelspec for the virtual environment.

Meaning this:

{
 "argv": [
  "python",
  "-m",
  "ipykernel_launcher",
  "-f",
  "{connection_file}"
 ],
 "display_name": "My Test Kernel",
 "language": "python",
 "metadata": {
  "debugger": true
 }
}

is the same environment as this:

{
 "argv": [
  "python",
  "-m",
  "ipykernel_launcher",
  "-f",
  "{connection_file}"
 ],
 "display_name": "Python 3 (ipykernel)",
 "language": "python",
 "metadata": {
  "debugger": true
 }
}

They both launch the kernel the exact same way and we remove the custom one as a duplicate.

[rchiodo]

There is a bug though. If the custom kernel differs in any other way (like say the environment) it shouldn't be dropped as a duplicate.

@rchiodo Thanks a lot for your quick feedback.

the second kernelspec (even though it has a custom name) is really the same as the 'python3' kernelspec for the virtual environment.

That sounds reasonable, In my non-tested "steps to reproduce" I was aiming for a simple example so authors of this extension can reproduce this bug. I just tried them out and I can confirm that a new kernel with just a different name is hidden and not available through kernel picker.

But in my actual usecase where I found this name bug, argv of new kernel is not the same as argv of default kernel (for context please refer #7063).

So here's a working example to illustrate the problem:

Default Kernel :

{
 "argv": [
  "python",
  "-m",
  "ipykernel_launcher",
  "-f",
  "{connection_file}"
 ],
 "display_name": "Python 3 (ipykernel)",
 "language": "python",
 "metadata": {
  "debugger": true
 }
}

Custom Kernel :

{
    "argv": [
     "python",
     "-m",
     "ipykernel_launcher",
     "-c",
     "print('hello')",
     "-f",
     "{connection_file}"
    ],
    "env": {
       "PYTHONPATH": "/some/random/path"
     },
    "display_name": "new_kernel",
    "language": "python",
    "metadata": {
     "debugger": true
    }
}

The addition of env and -c print('hello') was sufficient for the jupyter extension to not hide the new kernel.

Now the kernel picker shows two kernels with the same name:

selecting it shows that the new kernel is also started properly:

Finally, here are the logs from my updated example posted in this comment

There is a bug though. If the custom kernel differs in any other way (like say the environment) it shouldn't be dropped as a duplicate.

I don't think it is being dropped though. It is just coming up with the same name without any way to differentiate..

[DonJayamanne]

I have already created a bug where we don't list the kernel specs with custom env variables, it is already part of the Jan milestone.
I think we can close this as a duplicate of that issue
#7719

[rchiodo]

Should be fixed now.

[IanMatthewHuff]

I don't believe this is fixed.

I have two kernelspecs installed into .debugEnv and one of them has a custom display name. But we are not showing that Display name. If I activate .debugEnv in the terminal and start Jupyter it sees the display name of the new kernel that I added:

[IanMatthewHuff]

Reactivating, but doesn't seem like a huge fix this late in release cycle, so moving to Feb.

[DonJayamanne]

Should now be fixed.

[IanMatthewHuff]

Looks good now:

It's listed as New Python Kernel Env not at .debugEnv now.
