Can any one please help me to fix this issue ?

Ah, that might be numpy being more strict than the version I was using. Can you try adding int() around the two float() calls? Like:

newY = int(ceil(spectrogram.shape[1] / gridSize) * gridSize)
newX = int(ceil(spectrogram.shape[0] / gridSize) * gridSize)

for lines 21/22?

If that works I can change it in the repo.

I have to change it to.
ceil(spectrogram.shape[1] / gridSize) * gridSize ==> spectrogram.shape[1]
