hyperas: IndentationError: unexpected indent

Hey, I just installed on python 3.4.2 and I’m using the PyCharm IDE. I’ve opened the example file in my ide and attempted to run it. The following error occurs:

Using Theano backend.

IndentationError: unexpected indent

I understand that this may be because there is a mixing of tabs and spaces? I will be attempting to resolve it under that understanding next and update here if that is the case.
