When creating a docker image from the dockerfile, I am not able to create it successfully. When running the script present here, install-dmlab.sh. The building process fails since bazel installed via the script is (8.0.1) and I think it no longer allows building things using older python. Does the script need to change in order to install older version of bazel?

Yeah either that or dmlab needs to change their BUILD file to remove the Python 2 rules (which aren't used anyways).
