/usr/lib/python3.5/importlib/_bootstrap.py:222:

RuntimeWarning: numpy.dtype size changed, 

may indicate binary incompatibility.

Expected 96, got 88 return f(*args, **kwds)

This warning is harmless. 

This is due to the Numpy version 1.15.0 or 1.15.1

You can ignore this. 

Or you can go back to Numpy version 1.14.5 

You can do this by

conda install numpy1.14.5

Or, you can wait until Numpy1.15.2 is released.
