• Type of virtual environment used (N/A | venv | virtualenv | conda | ...): venv (with numpy installed)
• Relevant/affected Python packages and their versions: any external package (numpy, matplotlib...)
• Relevant/affected Python-related VS Code extensions and their versions: Microsoft Python v2020.10.332292344
• Value of the python.languageServer setting: ?

[NOTE: If you suspect that your issue is related to the Microsoft Python Language Server (python.languageServer: 'Microsoft'), please download our new language server Pylance from the VS Code marketplace to see if that fixes your issue]

I installed Pylance as suggested above, still same problem

Expected behaviour

Show documentation or function parameters for numpy.array

Actual behaviour

No showing anything

Thanks for the bug report! We investigate issues in order based on priority and severity, which includes the impact it has on your ability to use the extension to do productive work, and the number of people affected. If other users come forward and leave a comment demonstrating they are seeing/reproducing the problem then we will raise this issue's priority.

If you think your issue is more of a question or configuration problem rather than a bug, please ask on Stack Overflow with the visual-studio-code and python labels for help.

Thanks for your understanding and patience!

Hi, can confirm this also affects me — after the update autocompletion for pytorch and numpy stopped working. Same vscode / python extension versions as for the topic starter

[JanHomann]

I can also confirm the issue. Matplotlib seems to be okay. Pandas is fine too on my end.
Actually, it only doesn't seem to work with np.array. All other np functions seem to work. Also, it seems like from the symbol that np.array is not identified as function, but 'import'.

I have the same problem

[shraddhazpy]

Suggestions and autocomplete not working for me either

[BenjaminJenney]

Not working for me as well!

[aamattos]

Same problem here

[enkeyz]

Same problem.

[jcntrl]

Can confirm this is an issue for me as well. Seems to be isolated to numpy module but inconsistently as some functions within numpy work; other modules' Intellisense works ok.

MacOS v11.2.
VSCode v1.53.1
Python3 (several versions)

[uluturki]

I am having the same issue with numpy, and scipy. I'm using VSCode from Windows with WSL2 and use conda as the package manager if it's relevant. I'll come back to edit this message with details when I get a chance.

[thsubaku9]

Came here to report the same issue. Using vscode on M1 Mac Air and certain functions just aren't showing up in auto prompt (for e.g. frexp and ldexp)

Which language server are you using?

Which language server are you using?

Hi. After almost half a year and this issue still open.
Currently, I don't experience the same problem. (I changed python, installed new os, new vscode...)
So I may want to ask the people who got the same problem to contribute their language setting.

So, please replay with your python language setting:

Not one of the previous people, but I'm experiencing (I think) the same problem, with all python packages at the moment. All intellisense hints/suggestsions/autocomplete are stuck on "loading".

Even "go to definition" gets stuck both for functions from packages (e.g. numpy), as well as functions defined in the same directory. The blue line loading animation at the top of the window just keeps going for a while before it seems to give up.

I just upgraded to VSCode 1.54.3, which I think initiated the problem. I'm on macOS Mojave (10.14.6) and using miniconda3 with conda environments. The environment seems to load fine, and the linter seems to be aware of which packages are installed. Using Jedi for python language server (version 0.18.0), pylint version 2.7.2. And Linting for python is enabled in my User and Workspace settings.json.

Which language server are you using?

@ShlomiRex @kimadeline

I use the following language server:

Name: Pylance
Id: ms-python.vscode-pylance
Description: A performant, feature-rich language server for Python in VS Code
Version: 2021.3.3
Publisher: Microsoft
VS Marketplace Link: https://marketplace.visualstudio.com/items?itemName=ms-python.vscode-pylance

[kimadeline]

There are known issues with Pylance:

• numpy: Missing info for numpy pylance-release#150
• matplotlib: Intellisense is messed up. Function information and type checking is useless for matplotlib (and other modules like numpy)  pylance-release#844

Please follow these issues, since the stubs are provided/used by Pylance.

@Aman-A, please open a separate issue, since it sounds like nothing was working, instead of incomplete autocompletions.

Closing since the original issue was resolved.
