Every Python developer has hit this: you upgrade numpy or pandas, and code that worked yesterday breaks today.
I built an open dataset for exactly this problem. DepDoctor is 6,204 examples of Python code broken by a dependency upgrade, each paired with the fix and a short note on the API change that caused it. It is a mixture of real cases mined from public GitHub commits and synthetic cases generated from a database of known breaking changes.
A few things I tried to get right:
- 935 "leave it alone" examples, to teach a model restraint, not just what to change.
- Honest evaluation: a fine-tuned Qwen2.5-Coder-7B gets 62% of fixes fully correct. I report that, not just the 97% text-similarity score that hides the truth.
- The main failure mode, over-editing, is measured and explained rather than buried.
Dataset, fine-tuned model, and a live demo are all open in one place:

Feedback welcome, especially from anyone working on code repair or API migration.
