Issues with Rebound and Backspin Using Pre-trained Model #9

Open zhanglbthu opened 1 month ago

Hello, When I use the trained model to reproduce the rebound and backspin action, something goes wrong, like the following:

Has this happened to any of you, please? Thank you for your reply.

Btw, the trained model was downloaded from the official.

Hi, these issue happens in this code version. There are mainly two reasons: (1) the reference data is not accurate, especially the "rebound" data; (2) the current code uses the first frame to initialize the env. In our follow-up work, using accurate HOI data and applying random frame initialization can significantly improve imitation performance.
