Python extension is broken

[abhishekkrthakur]

It seems like the python interpreter cannot be selected in 3.7.1

Command 'Python: Select Interpreter' resulted in an error (command 'python.setInterpreter' not found)

[vnijs]

Things were working nicely in 3.6.2 but not in 3.7.1 or 3.7.2. With the latest version of the python extension it is trying to also load a jupyter extension and dying there.

[code-asher]

Looks like we have another broken extension...I wonder why it works in 3.6.2 though. Maybe it's pulling a different version of the Python extension.

I think it started to break with Python 2020.11 where it separated Jupyter into a standalone extension and was dependent on it:
https://github.com/microsoft/vscode-python/releases/tag/2020.11.358366026
"Code for Jupyter Notebooks support has been refactored into the Jupyter extension, which is now a dependency for the Python extension"
The previous python (2020.10) worked for me with code-server 3.7.2.

[vnijs]

@zhizheng-1 Thanks! I can confirm that the 2020.10 version (link below) does indeed work with code-server 3.7.2

https://github.com/microsoft/vscode-python/releases/tag/2020.10.332292344

[bruwozniak]

The problem I believe is that you are shipping the 2020.12.0-dev version of the Jupyter extension in your extension gallery (presumably automatically built from https://github.com/Microsoft/vscode-jupyter), whereas in Microsoft's gallery the versions are different: https://marketplace.visualstudio.com/items?itemName=ms-toolsai.jupyter, the latest one being 2020.11.372831992

[code-asher]

Ahhhhhh I see. It doesn't look like they use GitHub releases or tags so our builder must just be continually building off master and breaking all the time as a consequence.

[ttthree]

Any timeline to get this fixed or is there any workaround ? :)

[code-asher]

No timeline yet; I'm not entirely sure we can do anything differently from our end other than manually updating the version which won't be sustainable. Maybe we can get the vscode-jupyter repo to start adding releases to GitHub, then our marketplace can just pull those in instead of building itself.

[vnijs]

@ttthree I installed the latest extension versions of jupyter and python from marketplace (link below for jupyter) and that seems to work.

I build code-server into a Docker image I use. I got it working by first installing the python extension (which now automatically installs the 2020.12.0-dev jupyter extension mentioned above from code-server. I then install the jupyter vsix linked above with --force because it sees it as an older version. I then add "extensions.autoUpdate": false to my settings.json file so it doesn't automatically update to the incompatible version upon startup.

[gogobd]

@jhallas Could you eventually share the Dockerfile you are using? I've been downgrading to 3.4.1 and for quite a long time now...

[benz0li]

@gogobd I'm currently using the following code in a Dockerfile with code-server 3.7.4:

[...]
&& code-server --install-extension ms-toolsai.jupyter-2020.11.399280825.vsix || true \
&& code-server --install-extension ms-python.python \
[...]

See #2355 (comment) about standard bash ignore error || true.

Hmm.. I found 3.5 to work for me!

Hi, Sorry for the delay. I can't share the Dockerfile but this is what I do:

1. Install code-server
2. Copy in external vs code extensions
3. code-server --install-extension (python extension)
4. code-server --install-extension (jupyter extension) --force
5. copy custom settings.json to /home/jovyan/.local/share/code-server/User/ with "extensions.autoUpdate": false line

Thanks to the comments I found here here that made it work for me...
I fixed and edited this comment (settings.json wasn't in the right place)

[pseeth]

By any chance, is there a timetable for getting the extension working again? I really want to use code-server, but as an ML person trying to use code-server on remote GPUs, the Python extension not working is a showstopper for me. Hoping it gets fixed soon, as I'd love to use this.

[jhallas]

@pseeth I think it works even with the most recent version as long as you download the extension vsix for python and jupyter from the vs code website manually install with the considerations I listed.

[oxy]

Hey, I think I managed to get it working - you may need to "reset" your code-server instance by removing ~/.local/share/code-server (warning: this removes any custom configuration, all extensions, and your HTTPS certs if you asked code-server to manage them!), but I just tested this myself and Python should work now, fingers crossed.

I did some manual wrangling and downgraded the Jupyter extension and upgraded the Python extension that's being served; it may break every time MS pushes a new update, but I'll force-downgrade it whenever its needed.

Closing for now!

[Ki6an]

was facing a similar issue,
by using the older version of python was able to fix the issue :

next, select this version 2020.10.332292344 or 2020.5.86806.

now I'm able to use pylint and debugging too

[maresb]

@Ki6an it's well known that it works with 2020.10.332292344, so you shouldn't need to go that far back.

@oxy, could you please provide more details? What are the specific versions of the Jupyter and Python extensions that you're using?

[phisanti]

I totally agree with @Ki6an, but the problem is I cannot run ipython widgets in that version. More precisely, I would like to run the nglview plug-in for my work. Do you know how I could run that widget in the 2020.5.86806 version? Moreover, what is the difference between the two versions so that the 2020.5.86806 works but 2020.10.332292344 doesn't? Is there any "debug" option that we could activate to see how each version runs?

[oxy]

Alright, latest versions that work for me are Python v2021.2.633441544 and Jupyter 2021.2.0 - and they should be the latest on our gallery.

[phisanti]

I have just tried Python v2021.2.633441544 and Jupyter 2021.2.0 (using code-server 3.9.1) as @oxy says and I can confirm that it works. However, I might seem a bit thick but I don't understand why. I thought that code-server depended on open-vsix and they have not released a new version, so why is that suddenly now works?

[abhishekkrthakur]

doesnt work for me. im on 3.9.1 and updated python extension to 2021.2.633.....

[rushtehrani]

It's also working for me with code-server 3.9.1 and ms-python 2021.3.658691958.

We were hoping that we could switch from our internal gallery to OpenVSX and then hope upstream/OpenVSX could sort out the versioning issues; but then I decided to just manually override the versions we're serving right now, since we're blocked on web extension support for OpenVSX.

I didn't expect 2021.3 to work as that depends on VSCode 1.54, which we're yet to update to.

[wzrzt]

It's also working for me with code-server 3.9.1 and ms-python 2021.3.658691958.
May I know how to install ms-python 2021.3.658691958 into code-server 3.9.1, please?
I can't see this version on my code-server 3.9.1. And I downloaded it from vscode-extension-market and it can't be installed and told me not compitable with vscode v1.53.2.

I went back and checked and it looks like even though I explicitly set the version to 2021.3.658691958 in my Dockerfile:

RUN code-server --install-extension [email protected]

The extension page in the IDE is showing that 2021.2.633441544 is installed:

So --install-extension probably fell back to the latest supported version.

The good news is 2021.2.633441544 is working.

[ddurham2]

@rushtehrani, that's probably due to #2626

[DavidTWynn]

After I set an env variable to install python3 I could install 2021.3 of the ms-python extension.

[gogobd]

it's weird but all the previous workarounds don't work for me any more... I get ChunkLoadError with 2020.10.332292344/ms-python-release.vsix and everything else I tried didn't work either. Is there a known working solution for docker currently?
I'm trying to get Jupyter Notebooks to work again.

[MarcSkovMadsen]

I can get ms-python v2021.5.842923320 and ms-toolsai.jupyter v2021.3.0 working.

But using the latest version ms-toolsai.jupyter v2021.5.0 does not work.

[gogobd]

I can get ms-python v2021.5.842923320 and ms-toolsai.jupyter v2021.3.0 working.

But using the latest version ms-toolsai.jupyter v2021.5.0 does not work.

Is that with 3.10.x? (I’m asking because I completely downgraded to 3.9.x because Jupyter didn’t work.)

What is 3.10.x referring to?
