In deep learning sometimes the loss diverges to infinity which results in loss becoming nan.

This results in an exception in the python code:
HTTPError: 400 Client Error: Bad Request for url: http://localhost:8100/data

Also the error in the node server:

SyntaxError: Unexpected token N

Oops! This is a pretty silly error -- thanks for catching it. Will fix this is the next patch.
