Error running train.py

Hi, I am getting this error when I try to run the training. I am using python3.6.

Thank you

Hi,

I believe this is caused by a change in Python 3 with map, namely you need to do

np.array(list(map(lambda (m, p): griffin_lim(m, len_frame, len_hop, num_iters=num_iters, phase_angle=p))

to cast the map object to a list, so it can be converted into an np array.

When I changed it like you said, It always say error. I used numpy==1.14.2, because I can't install numpy==1.3.0

return np.array(map(lambda m: lambda p: griffin_lim(m, len_frame, len_hop, num_iters=num_iters, phase_angle=p), zip(mag, init_phase)))

It seems work.

Made a fork that works in python3 -> https://github.com/jadujoel/music-source-separation/tree/py3
