Hi,

as stated by the error, you must specify all the arguments

example: np.apply_along_axis(lambda x: librosa.feature.melspectrogram(y=x,sr=40), 0, sample)

instead of: np.apply_along_axis(lambda x: librosa.feature.melspectrogram(x,sr=40), 0, sample)

if u support the project, don't forget to leave a star ;-)
