Error while activating Python: {}

Some search showed the issue #296, but downgrading to 2021.5.926500501 of the Python extension might not be sensible. Further search lead to https://forum.manjaro.org/t/vscode-intellicode-language-server-error-with-python-with-fix/146447 where downgrading Pylance to v2023.6.40 did the trick.

Testing all Pylance versions beginning with the current one (v2023.10.10) down to v2023.6.40 I was able to reproduce the error with every version except for v2023.6.40.

Not sure if this issue is properly placed here, or belongs to the Pylance site, also considering I got a fix to use intellicode for my use case, but for further bug fixes and as a resource for persons with the same issue, this might help.

Let me know if there is more data / logs needed to find the cause here.

I am getting the same error messages on Windows 10 when opening a .py file.

Had the same issue. I had re-installed both extensions but same error persisted.

I rolled-back to Microsoft Python extension version v2022.14.0 and its working.

Downgrading Python extension (ms-python) from v2023.20.0 to v2023.4.1 solved the problem in VSCodium 1.82.0 with Python 3.11.7 on Windows 10 21H1.
Other newer versions of the extension refuse to load properly (because of incompatibility?).

I am having the same issue. using latest versions of python, pylance, intellisense and other extenions gives
"Error: command 'python.intellicode.loadLanguageServerExtension' not found"

however, downgrading to pylance varsion 2023.6.40 does not give this issue.

Having the same issue here, It seems the issue is present to any version after 2023.6.40.

Same issue using code from the arch repo (code-oss). Downgrading Pylance to 2023.6.40 seems to work fine but i'd still rather not run a 1y old version of an extension.

[kuolemaaa]

It is INCREDIBLE that after a whole year this is still an issue

Manjaro Linux
code 1.90.0-1
pylance 2024.6.1
intellicode 1.3.1

I met the same problem here. The version of Pylance is v2024.7.1, and IntelliCode v1.3.1. Sorry that I cannot show the log here because I was using offline in my company.

Problem persists.
Downgrading Pylance to v2023.6.40 did the trick though.
Just comment to let the devs know the problem still hasn't been fixed yet
