Please update the python extension to the latest version
or install the pre-release version directly. ( may be more useful to you )
this will basically solve your problem.
If the error continues, follow these steps:
Answer from JialeDu on Stack Overflow
- Uninstall Python extension (if you have pylance uninstall it first). Uninstall any other extension that is failing.
- Close all instances of VS Code.
- Go to, %USERPROFILE%/.vscode/extensions (on windows) or ~/.vscode/extensions on Linux/Mac.
- Delete any folder with the name starting with ms-python.python*
- Start VS Code, and install Python extension (also pylance if you uninstalled it in step 1).

I was having this issue and tried the above answer and it still didn't work. It turns out I hadn't installed python on my system yet. I didn't realize because I normally use it remotely.
From the VSCode documentation:
Quick start
- Step 1. Install a supported version of Python on your system (note: that the system install of Python on macOS is not supported).
- Step 2. Install the Python extension for Visual Studio Code.
- Step 3. Open or create a Python file and start coding!

Python Extension loading issues
Please have a look at this issue: Python extension loads very slowly: unresponsive. Try insiders version of the extension, and see if it helps with this issue. You can always download and install latest insiders build form here https://pvsc.blob.core.windows.net/extension-builds/ms-python-insiders.vsix .

FIX: I fixed it! turns out i didn't completely remove vscode from my pc, so i deleted the config and cache folders and reinstalled vscode and it works perfectly now! still curious as to what the hell caused it...
at the bottom left of vscode it keeps saying "Python extension loading" and it never finishes, i tried reinstalling all the extensions, updating vscode, rebooting the system, and disabling the other extensions one by one, but to no avail.
it was working fine before, any help would be appreciated!
EDIT: im using linux (kubuntu 20.04) and i can't do anything python related (run scripts, formatters not working...etc)
I'm having a problem where the python extension has a very long loading time. I've tried unistalling and reinstalling but that hasn't worked. Any advice on what to do?
These steps solved my issue:
- Open VS Code
Settings - search for
Python Locator - switch from
nativetojs. - restart the vs code
Same problem here...the link below solved it for me.
- In VS Code, type Ctrl + Shift + P
- Type Python: Clear Cache
- Select option Python: Clear Cache and Reload Window

OK - I deleted the VS Code profile folder
'%APPDATA%\Roaming\Code
and installed fresh extension along with miniconda, and it is working fine.
This seems to be an annoying problem that is caused by other extensions. Best way I fixed mine was:
- To disable all the extensions
- Enable ms-python extension
- Reload vs-code and voila, it's all fixed
I'm starting to mess around with python again in my free time and I'm having issues with the python extension. I only have 3 extensions installed. C#, PowerShell, & Python. All from Microsoft. I've uninstalled/reinstalled VS Code. I'm running 3.8.5 python.
When I try to add python (control + shift + p) it spins at loading the extension and comes back with reload, wait, or cancel. If you hit wait afew times, it will eventually load the python extension. The machine is an i7 4xxx, 32 gb of ram, ssd, ect.... I'm seeing no CPU, RAM, or Disk spikes during this time.
Has anyone seen anything like this before? Is there anything in the event viewer log that would help?
*** EDIT ***
I also tried it with the other extensions disabled.
Note that telemetry.enableTelemetry as described in the original answer has been deprecated. Please use this instead:
"telemetry.telemetryLevel": "all|error|crash|off"
Original answer
Try to disable telemetry in the user settings:
"telemetry.enableTelemetry": false
Change back to an older version, I'm also having this issue, I switched back to the older version and now its fixed.
Recently updated my laptop, and after installing VS Code and Python on the new machine, I've noticed that the Python extension takes forever to load any time VS Code is (re)started. I haven't timed it exactly, but probably at least a minute or more, just to load an extension on a 'gaming' laptop with oodles (technical term!) of RAM, disk space, and processor power to spare.
Nothing particularly exotic as far as extensions loaded - Python (obviously), Pylance, Jupyter, Remote - WSL, Vim, Visual Studio Intellicode and vs-code icons. Even with everything disabled but Python, Pylance and Jupyter, it doesn't change - and the extension very obviously holding things up is the Python one.
Nothing too exotic about the Python install... vanilla 3.8.6, from python.org, using virtualenvs for development. Even with the base install, and nothing much beyond pylint, black and virtualenvwrapper-win installed via pip... this seems really, really, really odd.
Any ideas?
