incomplete requirements.txt file

[gaetanbahl]

Hello,

The requirements.txt file is incomplete. When trying to run tools/infer.py, it's missing open3d, joblib, pandas, trimesh, einops, h5py, and others.

Also, requirements.txt should include specific versions of packages, otherwise it is guaranteed to break in the future.

Thanks.

When I try to run tools/train.py,I encounter more missing dependencies.
