[83] Example to run a deep learning demo

[thunterdb]

This PR contains a script that runs a deep learning example. This only works with TFrames 0.2.8+

TODO: Note that this requires tf-slim to work. Since tf-slim is not properly packaged, this requires some extra installation instructions to properly work.

hey, i was also trying to achieve this, from the official example code, so there is no notion of sc.broadcast(tensorflow_checkpoints) and just works on a input dataframe? I was wondering how the parameter actually passed to the workers

[yupbank]

just answering my own question, convert_variables_to_constants is doing the trick

[yupbank]

so i ported one without the slim thing are you ok if i make another commit to this?
