dependencies with a non-conda installation

[pojeda]

the cluster I use doesn't support "conda" so I am trying "pip" and "python setup.py". In the installation instructions of the software the "conda" instructions are provided. I have tried these two but I get an error due to incompatibility of versions:

error: torch 1.7.1 is installed but torch==1.9.1 is required by {'torchvision'}

Then, I tried torch==1.9.1 but in this case, there is a conflict with torchvision:

The conflict is caused by:
The user requested torch==1.9.0
torchvision 0.9.0 depends on torch==1.8.0

I wonder if you have some instructions by using "pip" or "python setup.py" instead of "conda"? Maybe you could provide me with the versions' number of the packages for dependencies? I would be really grateful.
