Provide requirements list

[ajrferrari]

Hi,
I am trying to run a protocol inspired by the example20_protein_demo.ipynb for a few backbones. I followed the instructions provided in installation but not all requirements are readily available.
For example, if I try to import proteinsolver

import proteinsolver
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/projects/p31346/cassie/proteinsolver/proteinsolver/__init__.py", line 4, in <module>
    from . import *
  File "/projects/p31346/cassie/proteinsolver/proteinsolver/utils/__init__.py", line 3, in <module>
    from .scatter import *
  File "/projects/p31346/cassie/proteinsolver/proteinsolver/utils/scatter.py", line 1, in <module>
    import torch_geometric
ModuleNotFoundError: No module named 'torch_geometric'

If I import torch_geometric
pip install torch_geometric
and then try to import protein solver again

import proteinsolver
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/projects/p31346/cassie/proteinsolver/proteinsolver/__init__.py", line 4, in <module>
    from . import *
  File "/projects/p31346/cassie/proteinsolver/proteinsolver/utils/__init__.py", line 3, in <module>
    from .scatter import *
  File "/projects/p31346/cassie/proteinsolver/proteinsolver/utils/scatter.py", line 1, in <module>
    import torch_geometric
  File "/home/ajf4103/anaconda3/envs/proteinsolver/lib/python3.7/site-packages/torch_geometric/__init__.py", line 4, in <module>
    import torch_geometric.data
  File "/home/ajf4103/anaconda3/envs/proteinsolver/lib/python3.7/site-packages/torch_geometric/data/__init__.py", line 1, in <module>
    from .data import Data
  File "/home/ajf4103/anaconda3/envs/proteinsolver/lib/python3.7/site-packages/torch_geometric/data/data.py", line 9, in <module>
    from torch_sparse import SparseTensor
ModuleNotFoundError: No module named 'torch_sparse'

When I try to install torch_sparse, I find a major error that I couldn't solve:

Collecting torch_sparse
  Using cached torch_sparse-0.6.14.tar.gz (51 kB)
  Preparing metadata (setup.py) ... done
... many lines ...

error: command 'gcc' failed with exit status 1
      [end of output]

  note: This error originates from a subprocess, and is likely not a problem with pip.
error: legacy-install-failure

× Encountered error while trying to install package.
╰─> torch_sparse


note: This is an issue with the package mentioned above, not pip.
hint: See above for output from the failure.

Would it be possible to provide the packages along with their versions as a requirement file to be installed?
Thanks,
Állan
