Incompatibility with transformers>=5.x #119
Description
Hi @ChenFengYe , I found that MotionGPT works correctly with transformers==4.57.1, but when upgrading to transformers==5.3.0, the model still runs but produces clearly wrong motion outputs with no runtime error.
The only noticeable difference is an additional warning about weight tying (shared.weight vs lm_head.weight) when loading the T5 model in v5.x, which does not appear in v4.x.
It might be helpful to specify the compatible transformers version in the requirements, so others don’t run into the same issue.
