Mostly minor comments. Only additional questions I have is:

  • Have you tested that all prior endpoints still work (for images)
  • Could you add an updated README to your PR that describes how to use the sentiment API?

yes, I will remove this and other debugging related print statements

I don't think we need this either, especially if we want to move to Python 3 down the line

We should either use print everywhere or logging everywhere (I vote logging)
