cannot import name 'Body' from 'smplx.joint_names'

[qaz8788817]

I encountered this problem when I tried to execute this command python transfer_model/write_obj.py --model-folder ./models/ --motion-file transfer_data/support_data/github_data/amass_sample.npz --output-folder transfer_data/meshes/amass_sample/ And here is the output:

But this problem wouldn't appear in Python Interpreter.

Can someone help me? Thanks.
