Plotting the spectrum in STFT/Stochastic/SPS/HPS model does not work.

#Same problem everywhere, TypeError: 'float' object cannot be interpreted as an index

STFT is solved :: #52

rolling back to numpy version 1.11.0 solves this issue. pip install numpy==1.11.0

i do not understand the sms-tools code well enough to revise it, but rolling back numpy is a solution.

I rolled back numpy to 1.11.0 as suggested. It seems that there are some incompatibility with numpy 1.12.1. After rolling back i get deprication warnings : "stft_function.py:70: VisibleDeprecationWarning: using a non-integer number instead of an integer will result in an error in the future"

@aamirmalik it's a known issue as it uses floats for array indices. It has been reported on the course forum, has a simple fix (wrap with int()), and doesn't cause any numerical problems.
