The code seems generally outdated

I've been trying to run the first tutorial and I'm still jumping through hoops to avoid errors.

I would like to have a pip freeze of a working environment, because the problem I'm facing now seems related to outdated features of PyTorch and PyTorch Lightning. The issue #7 is closed, but I don't think it should be. Either the code should be updated to work with current versions of the libraries or the requirements should be edited to a set of versions that works.

As a note, up until now I've managed to avoid the following problems:

• The instructions for the installation of smpl_derivatives are wrong. My solution seems to work: ModuleNotFoundError: No module named 'psbody.smpl.fast_derivatives.smpl_derivatives' #19 (comment)
• One of the configuration files is wrong, this seems to fix it: UnsupportedInterpolationType: Unsupported interpolation type resolve_mocap_subject #8 (comment)
• When installing Mosh++, I had to edit the version of Cython in the requirements
• PyTorch3D can't be installed with pip install -r requirements.txt. It has to be installed from source manually.
• mesh always imports the meshviewer module, which causes problems with OpenGL. For this, my solution has been to move the from OpenGL import GL, GLU, GLUT statement inside the functions, to avoid importing it until the moment it is necessary (because I don't care about visualization if I can't even run the model). The related issues are:
  • PyOpenGl GLUT linux MPI-IS/mesh#78
  • NotImplementedError: Platform does not define a GLUT font retrieval function mcfletch/pyopengl#71 (even when using Ubuntu the solution didn't work for me)
