Issue with Preprocessing MPII Dataset for Pose Estimation Project

[xiaoran-roosevelt]

Thank you for your work; it has been very inspiring. However, I encountered some issues when trying to replicate the experimental results. Specifically, I am having trouble with preprocessing the MPII dataset. Following the format in the README does not seem to work, and converting it to COCO format also leads to problems. Could you please provide guidance on how to preprocess the MPII dataset correctly so that I can successfully run the test code in the pose project?
