issue opening stft file

Mandars-MacBook-Pro:models_interface Mandar$ python models_gui.py
Exception in Tkinter callback
Traceback (most recent call last):

I also see this with Python 2.7.13.

A potential fix is to change line 59 to:

plt.pcolormesh(frmTime, binFreq, np.transpose(mX[:,:int(N*maxplotfreq/fs)+1]))

And line 70 to:

plt.pcolormesh(frmTime, binFreq, np.transpose(np.diff(pX[:,:int(N*maxplotfreq/fs)+1],axis=1)))

However I'm not 100% sure if this is entirely correct, since the step value is truncated and may not be quite the right value.

I don't understand how anyone could proceed past this point without seeing this error? 5000.0/fs will always be fractional for typical sample rates, and is unlikely to yield an integer for some typical N (power of 2). Is there a version of Python where slice indices can be non-integer?

Thanks David
The issue has been solved earlier.

@mandarptl Can you reference the commit or PR with the fix? All I see is a circular reference of issues between #49 (this one), #52 and #55.

@mandarptl has it really been solved? It affected me, on master, just yesterday. I didn't see a fix anywhere obvious.
