Which basically means you want to reshape with the earlier index varying faster. This is fortran order (in the simplest case for two axes being reshaped). So you can do: arr.reshape((7, 24, -1), order="F") otherwise, if order seems too confusing or dangerous. Just transpose the two axes first: arr_r = arr.transpose((0, 1, 3, 2)) arr_r = arr_r.reshape((7, 24, -1)) - Sebastian > [0,0,0,0] -> [0,0,0] > [0,0,1,0] -> [0,0,1] > [0,0,0,1] -> [0,0,2] > [0,0,1,1] -> [0,0,3] > ... > > What might be the simplest way to do this? > > ------------ > A different question, suppose I just want to stack them > > [0,0,0,0] -> [0,0,0] > [0,0,0,1] -> [0,0,1] > [0,0,0,2] -> [0,0,2] > ... > [0,0,1,0] -> [0,0,1024] > [0,0,1,1] -> [0,0,1025] > [0,0,1,2] -> [0,0,1026] > ... > > > > _______________________________________________ > NumPy-Discussion mailing list > NumPy-Discussion@scipy.org > https://mail.scipy.org/mailman/listinfo/numpy-discussion >
