DTW test/error/ resampy.filters.get_filter

I’m getting an error, it may be related to my environment, however this case appears to indicate get_filter is not returning the expected arguments

---> 23 BW_BEST = resampy.filters.get_filter('kaiser_best')[2]
IndexError: tuple index out of range

import librosa
D, wp = librosa.dtw(x, y, subseq=True)
print(d)

y=np.random.randint(0,255,(1024,1)) rosadisp.specshow(librosa.stft(y), y_axis=‘linear’)

Two problems here, #1 integer not float, #2 and passed through resampy

Possibly a dimension check at core/audio.py here may warn the user and exit/error out. BW_BEST = resampy.filters.get_filter(‘kaiser_best’)[2] BW_FASTEST = resampy.filters.get_filter(‘kaiser_fast’)[2]

It was my error on the input format of the sound signal/array, all set.

Glad to hear! This does seem like a failing of our exception handling / input checking though. Would you mind providing a minimal (self-contained) example that triggers the above behavior so we can detect it going forward and provide a more useful error message?

scikit-learn is typically sklearn on windows

Yes, but we report package names to match their pypi name, not the python package name.

Thanks! I’ll stick that on the todo list.
