Can't select Python interpreter in Cursor, even though it exists

Update: The Problem is solved. Check the updated Answer.

Old Answer: (Partially solve the problem)
it is annoying, the code runs, and everything works fine, but the cursor can't see the interpreter, making it even show a linter configuration issue like (import of Matplotlib can't be solved).

Solution would be:

using the code runner extension type ctrl +shit+x and install it then
Put the interpreter manually in json setting.

{
  "code-runner.executorMap": {
    "python": "C:\\Users\\--\\anaconda3\\python.exe -u"
  },
  "code-runner.runInTerminal": true,
  "python.defaultInterpreterPath": "C:\\Users\\--\\anaconda3\\python.exe"
}

And also to not show the import unsolved warning, do this:
create folder named .vscode and inside it make a file named setting.json, then put this code inside it

{
    "python.defaultInterpreterPath": "C:\\Users\\--\\anaconda3\\python.exe",
    "python.pythonPath": "C:\\Users\\--\\anaconda3\\python.exe"
}

Updated Answer Fully solved the problem.
Solution:

in setting.json if your language server is none change it to "Default"

"python.languageServer": "None"

"python.languageServer": "Default"

Also reinstall/install pylance by using following command in terminal
cursor --install-extension ms-python.vscode-pylance

Then restart the IDE.

Make sure you have installed

• Python (ms-python.python)

• Cursor Pyright (anysphere.cursorpyright)

Disabling the Python Environments extension and the restarting cursor fixes it for me.

First, make sure which Python version Cursor is actually using.
Open the integrated terminal and check the Python version that is active.

If things still do not work, try installing ipykernel manually, this commonly causes issues with notebooks as ipykernel must be installed in that exact Python environment. Then restart Cursor.

After that, select your interpreter again and confirm you are choosing the correct Python version, in your case Python 3.11.

Finally, open a notebook and manually choose the kernel that matches that Python version.
