Python 3 support enabled on NVCR.io?

[nhubbard]

Hi there. Just checking out the latest version of DIGITS on NVCR.io, and found that the latest image is tagged as 19.12-{tensorflow,caffe}-**py3**. Is this a mistake? If not, when will the repository be upgraded to Python 3? Thanks!

It's not a mistake, no. The latest NGC builds of DIGITS do support Python3. The source code is available inside those containers (in /opt/digits) if you want to see the changes we've made to enable that; sorry the GitHub branches have lagged behind a bit here. We'll keep this issue open until we update the branches on GH with the latest code.

Thanks, Cliff
