VS 代码 python 自动完成非常慢

Question

I have an issue using python for VS code on windows.

The autocompletion and color syntaxing is very slow (more than 153secs). I tried to disable all extensions as mentionned here Visual Studio Code Intellisense is very slow - Is there anything I can do? but without any improvement. My python file is very small (60 lines).

[Info  - 13:49:36] (32004) [IDX(2)] Long operation: index libraries c:\Users\XXX\XXX.py (2089ms)
[Info  - 13:49:36] (32004) Indexer done(2). indexed 504 files
[Info  - 13:52:07] (32004) [BG(1)] Long operation: getSemanticTokens full at c:\Users\XXX\XXX.py (153210ms)
[Info  - 13:53:43] (32004) [FG] Long operation: completion at c:\Users\XXX\XXX.py:33:12 (5334ms)

Any tips to trouble shoot my issue?

Edit:

• Python 3.10.1 - 64bits
• Pylance V2022.2.1
• VScode 1.64.2
• Windows 10

I a similar problem yesterday and tried to reinstall VSCode but pylance was still super slow (normal on start but slower and slower).

This morning, I tried to install an older version of PyLance extension (v2022.1.5) and it seems that now it works properly.
