this is the issue which it's showing while running the docker file

The command '/bin/sh -c /home/user/miniconda/bin/conda create -y --name py36 python=3.6.9 && /home/user/miniconda/bin/conda clean -ya' returned a non-zero code: 127

Thanks for the report, I believe that the issue is that the download request for miniconda now responds with a redirect, so I need to update the curl command to follow redirects. If you want to try to fix that yourself right now, edit the following line of whatever Dockerfile you're using to be curl -sLo instead of curl -so:

docker-pytorch/Dockerfile.template

Line 28 in 3df310a

    
           RUN curl -so ~/miniconda.sh https://repo.continuum.io/miniconda/Miniconda3-4.5.11-Linux-x86_64.sh \

I'll probably push a fix to this repo sometime tomorrow.

Fixed in 537d896.
