about ”Reference Manipulation Plan Generation“

[sherlock-lelouch]

Hello, I found two demos when trying your code. At this stage, drawer_demo can be generated smoothly, but salt_demo will have such an error when executing 07_human_motion_reconstruction.py (the program cannot detect any human motion trajectory in your video data, resulting in subsequent processing failure). I would like to know how to fix it.
