installing ms-toolsai.jupyter and ms-python.python doesnt enable any apparent features in cursor desktop (win11). opening notebooks just shows raw notebook text. “data science” documentation seems to be out of date.
Hey there. We need to separate two things here.
Opening and editing ipynb files with notebook rendering instead of raw text is built right into Cursor. No extra extension is needed. Microsoft extensions like ms-toolsai.jupyter ms-python.python and Pylance are only licensed for official VS Code so they won’t work in Cursor.
To fix ipynb opening as raw text try these steps.
First remove or disable those MS extensions then reload the window with Cmd/Ctrl+Shift+P then Reload Window. A sideloaded extension might be interfering.
Next right click the ipynb tab reopen editor with Jupyter Notebook and set it as default. Check your settings for workbench.editorAssociations and remove any override that forces text editor for ipynb.
If it still won’t open after an update fully restart Cursor.
Note that running cells needs the Jupyter extension and a Python kernel but that’s separate from just viewing the notebook.
Give those steps a try and let me know if it helped. If raw text remains send a screenshot of the open ipynb tab and your list of extensions.
