Changes

Note the build flag, if it is not there, the container will not be rebuilt if the image already exists, even if there were changes in the code. You should see the base container image being downloaded (if not already on your system), and then the changes specified in the Dockerfile being made. Afterwards, the container is run, which should create similar output as if running it directly on your system. While we are at Note that I have baked artificial delay into the code, training is much slower than it, should be. This is so we can have time to try some other things we can do with running containers, which we do now. Stop the running container anytime using Ctrl-C.
