some problems with human model

[HanLiangJ]

Hello, thank you for your work!
I have some questions about human.dae model.

1. Why my animation only have human's skeleton and the skeleton is generated randomly every time?
2. I have an error"UserWarning：fail to import module _transformations". I have tried "pip install transformations" but the problem still exists. What should I do correctly?
