Python autocompletion doesn't work with VS Code Python extenstion (Pylance) #892

an4s911 · 2021-10-28T16:10:05Z

Describe the bug
When I am using VS Codium and have the VS Code Python and Pylance extensions installed and enabled, I don't get any autocomplete options or suggestions and it shows No suggestions.

As you can see I have enabled only the Python extension and it shows No suggestions. Now when I disable I get some suggestions but they are not Python suggestions, but rather just suggesting text from other parts of the file.

But not even this works when the extension is turned on.

Please confirm that this problem is VSCodium-specific

This bug doesn't happen if I use Microsoft's Visual Studio Code. It only happens in VSCodium.

Please confirm that the issue/resolution isn't already documented

I checked the Docs page and my issue is not mentioned there.

Desktop (please complete the following information):

OS: Ubuntu 20.04 LTS
Architecture x64
Version 1.61.2

I think I kinda figured it out. When I install the Python Extension it installs another extension along with it called Pylance. And that is the one that is causing this problem. When I disable Pylance the autocompletion works. I have to test it out on the original VS Code as well to know if it is a problem of Pylance or VSCodium. And if the problem is with Pylance [Hopefully] I will close this Issue

an4s911 · 2021-10-28T17:52:36Z

I tested Pylance on the original VS Code and VSCodium and it seems like the problem exists only on the latter. I don't know if this is a problem only for me or anyone else. So if someone else tested it out and comment their observations it might be helpful.

PS: To be honest, I don't mind using the Python Extension only (ie without Pylance).

@an4s911 confirmed here as well with version 1.61. It seems to me that the last working release is the 1.56

SebastianGrans · 2021-11-02T15:40:53Z

The issue is that Microsoft prevents PyLance from being used in non-official builds.
A workaround is to modify the product.json file, and set nameLong to "Visual Studio Code".

ghtmtt · 2021-11-02T16:02:16Z

@SebastianGrans thanks for sharing but still I don't get the extension working. I've changed the product.json file with the instruction of reddit but still nothing

SebastianGrans · 2021-11-02T16:24:46Z

@ghtmtt What does it say in the Python output terminal?

Before I change nameLong:

Starting Pylance language server.
Error 2021-11-02 17:21:36: Failed to start language server, Class name = r, completed in 0ms, has a falsy return value, Arg 1: <Uri:/home/grans/Documents/harvesters_gui/Utils/CameraCalibration.py>, Arg 2: {"sysPrefix":"/usr","envType":"Global","envName":"","envPath":"","path":"/bin/python" [... etc]

After I change, it simply prints:

Starting Pylance language server.

with no error after it.

ghtmtt · 2021-11-02T16:52:24Z

@ghtmtt What does it say in the Python output terminal?

if you mean running a file in the python terminal I can do it without any problem. I just have issues with the autocompletion

SebastianGrans · 2021-11-02T19:59:33Z

@ghtmtt No. What I mean is the output from the Python extension.

You can see its output by opening a terminal inside Codium, and then go to the output tab, and select Python. See the screenshot below.

ghtmtt · 2021-11-02T20:05:00Z

This is what I have

Could you post your user settings.json file?

It could also be an extension that is interfering, so try disabling all extensions that aren't needed and see if that helps.
It works for me with these extensions active:

ghtmtt · 2021-11-03T17:34:01Z

Could you post your user settings.json file?

{
    "python.autoComplete.extraPaths": [
        "/home/matteo/dev/qgis-master/output/python/qgis/",
        "/home/matteo/dev/qgis-master/output/python/"
    ],
    "workbench.colorTheme": "Quiet Light",
    "python.autoComplete.addBrackets": true,
    "python.pythonPath": "/bin/python3",
    "explorer.confirmDragAndDrop": false,
    "atomKeymap.promptV3Features": true,
    "editor.multiCursorModifier": "ctrlCmd",
    "editor.formatOnPaste": true,
    "editor.rulers": [

    ],
    "python.formatting.provider": "none",
    "[restructuredtext]": {
        "editor.wordWrapColumn": 80,
        "editor.wordWrap": "on",
        "editor.acceptSuggestionOnEnter": "off"
    },
    "workbench.colorCustomizations": {
        "editor.selectionBackground": "#ced12d",
    },

        "*.ipynb": "jupyter.notebook.ipynb"
    },
    "autoDocstring.docstringFormat": "sphinx",
    "python.analysis.completeFunctionParens": true,
}

I've disable most of the extensions but still nothing. No external API and not standard autocomplete

gerroon · 2021-11-04T19:00:10Z

I have the same issue on Windows 10, VsCodium 1.61.2

I originally was not getting even classes and functions in the outline so I removed Pylance, which helped with the Outline but I now have no autocompletion.

This use work fine in early versions this year but I cant tell the last working version.

Thank you, it worked for me too. 👍

ghtmtt · 2021-11-08T06:50:06Z

Thank you, it worked for me too. +1

I've already tried this solution but it never worked for me. BUT it seems that the combination of 2 different changes in the product.json file makes the things working again!

brccabral · 2021-11-15T00:50:38Z

where is "product.json" located?

brccabral · 2021-11-15T01:30:50Z

Found it, need to edit file prepare_vscode.sh before compile

daiyam · 2021-12-01T18:24:54Z

The python extension is tricky since it's using a closed source server (pylance).
I do believe that the best course of action would for some python devs to fork that extension and replace the closed source part with a new open source project.

clayrisser · 2021-12-03T07:21:41Z

Use the jedi language server instead of pylance.

Thanks. Just like some others have mentioned, this worked for me as well. I think I will close the issue now as the issue is solved for me as well as others.

If the above mentioned solution didn't work then try the below and it should probably fix it.

And I am closing this Issue. Thanks to everyone who helped and contributed ✌

asdorsey · 2022-03-24T17:28:55Z

Sorry for issue necromancy, but I found another potential solution today:
Uninstall the Microsoft Python extension and install the Pyright extension instead. It's still Microsoft, but it provides auto-completion and error checking, and works on VSCodium out of the box without modification.

an4s911 · 2022-03-25T08:15:25Z

@asdorsey Thanks. I will check it out
