Scipy kd-tree implementation throwing "negative dimensions"

Question

I get the following error seemingly every time I try to do anything involving a kd-tree. Strangely, just days ago this very code was working fine, and it is still working fine on my colleague's machine (we are using the same repo).

It seems to happen no matter what I pass in.

Can anyone offer any insights?

  File "filename.py", line 69, in methodname
    get_index = self.kd_tree.query(array_to_query)

    for c in np.ndindex(retshape):

    return array(a, dtype, copy=False, order=order)
ValueError: negative dimensions are not allowed

Never found out the answer but a forced reinstall of numpy and scipy fixed the issue.
