Incredible indeed! Just hunting down one of these bugs feels like a very time consuming endeavor. What's your approach for these more subtle numerical bugs?

- cinntaile 3y agoI'm gonna guess he tried to reimplement some of the work from the ground up and wondered why certain results looked like they did.
- danielhanchen 3y agoYep! The goal was to implement Gemma in Unsloth to make finetuning faster and use less VRAM, and my reimplementation seems to get different results than the current ones.
- danielhanchen 3y agoYe it was indeed very gruelling - but very fun!! I used torch.dist everywhere, read ll implementations side by side to compare them, and had to manually inspect losses, plot them etc. It's a bit hard to automate sadly, since new archs cause new issues.
