> It's pretty common that Python scripts require extra dependencies, even the tensorflow
model analysis TFMA example requires a different version of TF than the one we install by
default. While users can roll their own container or edit the Dockerfile, it would probably
be useful to provide an easier path to integrating their dependencies.
> While we support automatically installing the dependencies at runtime on the workers,
this can be very slow, especially for things like tensorflow, arrow, or other numeric heavy
code.
> Another alternative could be a simple script to augment the existing base image.
