ARTICLE AD BOX
I am using Visual Studio Code with the Jupyter extension to work with Python notebooks.
Problem description
When I open a .ipynb file in VS Code, the notebook never finishes loading kernels.
It stays on “Detecting kernels”(as shown in the right side top of image) indefinitely.
If I close the notebook tab and reopen it (without closing VS Code), the file either:
keeps loading forever, or
opens without any kernel attached
Restarting the notebook does not help.
Actual behavior
Notebook status shows “Detecting kernels” indefinitely
Ctrl + Shift + P → Select Kernel shows no available kernels
Kernel list never populates
Closing and reopening the .ipynb file does not resolve the issue
Expected behavior
VS Code should detect available Python kernels and allow selecting one.
Environment
OS: Windows 10 / 11
VS Code version: 1.107.1
Python version: 3.11.9
Extensions installed:
Python (ms-python.python)
Jupyter (ms-toolsai.jupyter)
