Description

https://github.com/2U1/Gemma3-Finetune

I made a code for who wants to use the huggingface version to finetune, and having difficult using some other frameworks like me.

This code only uses huggingface for fine-tuning the 4B, 12B and 27B.

Also, you can set different learning_rate for vision_tower and language_model. ( Also for the projector)

Feedback and issues are welcome!
