[Numpy-discussion] rollaxis and reshape
Wed Dec 10 14:54:13 CST 2008
I'm trying to split an array into two pieces and have the two pieces in a
Here it is in code, because that's hard to explain in words.
(4, 50, 3)
>>>new_data = numpy.zeros((2, 4, 25, 3))
>>>new_data[0,...] = data[:,:25,:]
>>>new_data[1,...] = data[:,25:,:]
(2, 4, 25, 3)
That works but when I try it with reshape the elements get in the wrong
place. I've tried various combinations of rollaxis before the reshape, but
can't get it right.
