Librosa.display.waveplot (np.array (f), sr = 22050) ----- AttributeError: 'module' object has no attribute 'display'

Due to changes in version 0.6.0

of, librosa

you get these errors. I fixed all issues at http://aqibsaeed.github.io/2016-09-03-urban-sound-classification-part-1/ and did work on Python 3, librosa = 0.6.0
