File length excess

Support Help

I am seeing this issue pop-up as an error which eventually leads to slow performance / freezing of IDE.

File length of "**********" is 96102164 which exceeds the maximum supported file size of 52428800

Is Cursor not suitable for use with Jupyter Notebooks? This notebook is fairly small (35 cells inclusive of markdown), however there are some large-ish numpy arrays (1.000.000 x 1) and a few plotly graphs which might have some dense json specs behind them.
At any rate this would be small compared to a notebook I typically use in VSCode.

Hey @al-zahr!

File length of "**********" is 96102164 which exceeds the maximum supported file size of 52428800

This message is coming from Pyright (specifically, Cursor’s fork of Pyright).

You can exclude these files in your VSCode settings. For example, if you’re encountering this issue with .ipynb files:

"cursorpyright.analysis.exclude": [
    "**/*.ipynb"
]

However, it may be better to exclude only the specific large files rather than all files of that type! Excluding these files will disable Python type checking and IntelliSense for them.
