The annotations are stored in a numpy ndarray format however the data type for the items inside this array is numpy void and numpy doesn t really seem to know the shape of them.
This can be disabled by setting the optional argument struct as record false.
You may have a mat file that you want to read into scipy.
Supports wav aiff via python s standard library and mp3 via ffmpeg.
By default scipy reads matlab structs as structured numpy arrays where the dtype fields are of type object and the names correspond to the matlab struct field names.
Or you want to pass some variables from scipy numpy into matlab.
