JupOtter: Cell-Level Bug Detection in Jupyter Notebooks

JupOtter is a newly introduced bug detection system tailored for Jupyter Notebooks, featuring a specialized tokenization strategy that maintains cell structure and a cell-level bug prediction technique. It utilizes the OtterDataset, which includes over 21,000 annotated notebooks for fine-grained bug detection, achieving F1 scores that outperform both static analyzers and large language models in two out of three benchmark datasets. This tool is significant for practitioners as it enhances the reliability of complex notebook-based applications by enabling more effective identification of bugs at the cell level.
