Form a big 2d array from multiple smaller 2d arrays

Question

The question is the inverse of this question. I\'m looking for a generic method to from the original big array from small arrays:

array([[[ 0,  1,  2],
             


        

Answer 1

Yet another (simple) approach:

threedarray = ...
twodarray = np.array(map(lambda x: x.flatten(), threedarray))
print(twodarray.shape)
