Cannot create a conda environment.

[LiubovShilova]

Hi! I have some issues with creating the environment. Both mamba and conda return error.

While running

conda env create -f conda.yaml

I encounter the error:

Could not solve for environment specs

You may want to try downgrading Pytorch and potentially python, let me know if this works.

It worked for me when installing the requirements via the requirements.txt file using pip instead.
