[Numpy-discussion] TypeError: only integer arrays with one element can be converted to an index

Are you sure you wanted to make `left` and `right` tuples that contain
just one element (which is a numpy array)? In your code, len(a1) will be 1.
Maybe I am misinterpreting your code, but I think you want this:
left = array([ 107, 594, 1082, 1569, 2057, 2545, 3033, 3520])
right = array([ 133, 621, 1109, 1597, 2085, 2573, 3061, 3550])
