including e.g. an iterator likerange(0,4,2)or list of ints like[0,2,3]. I confirmed this by looking in the source and I think this line is where anything that isn't a slice, int or bool is cast as anumpy.array:
Describe the bug Numpy deprecated their aliases of built-in types in NumPy 1.20 (https://numpy.org/devdocs/release/1.20.0-notes.html#deprecations) and that triggers a warning every time one of these aliases is used. I am using librosa 0...
