Training Kit-ML encountered dimension mismatch problem

[lixiang927047]

@ChenFengYe I want to use the framework of MotionGPT to train Kit-ML, but I have encountered a lot of dimensional incompatibility problems, most of which are due to the fact that the data set is only 251 dimensional and the network is set to 263 dimensional (probably because the number of summary joints in the Kit-ML data set is 21). The number of joints for HumanML3D is 22). What do I need to do with the Kit-ML data set before training? Or do different Settings in the training script?
