Flatten numpy array with sub-arrays of different dimensions

Question

This seems like a simple enough task, but I haven\'t found how to do it using numpy. Consider the example array:

import numpy as np
aa = np.arra         


        

Answer 1

You can use numpy.hstack

>>> np.hstack(aa)
array([13.16,  1.58,  1.2 , 13.1 ,  1.  ,  2.6 ])
