The docstring is a bit underspecified. The condition array *must* be a 1D array
with the same size *as the given axis* of the other array (using the convention
that axis=None implies operating over the flattened array).
There's simply no valid interpretation of this, for example:
compress(array([[1, 0, 0],
[1, 1, 0]]), arange(6).reshape(2,3))
since numpy arrays cannot be "ragged".
