"Jupyter Notebook Cell Duplication and Type Conversion During Edits"

Open stephendwolff opened this issue 8 months ago • 2 comments

Bug Description When Claude is editing Jupyter Notebooks with a simple code update, it can sometimes duplicate the cell, and the fixed cell is no longer a code cell. This gets quite confusing as it appears after the fixed cell, so it looks like nothing has happened.

  • Platform: macos
  • Terminal: pycharm
  • Version: 1.0.22

Curious if the model encounters errors trying other mechanisms before it adds the cell as a text cell? For example, did it first try editing a cell, but for some reason that failed and after a few times it finally adds the cell with the incorrect type?

I don't think so in this case. I think the issue might be that i had the notebook open, and had run cells (until one broke). In one case, I fixed a kwarg name (which Claude had got wrong), but then when the fix for the cell was applied, the kwarg was unfixed (by Claude). So, perhaps Claude didn't re-read the file (or the Jupyter notebook reader i see mentioned)

Fair enough bot. But this wasn't resolved
