The numpy C function import_array() needs to be called before the numpy array API can be used. Importing it once in the extension is not enough if more files are used by the extension - in this case the integrators.

The docs are here: http://docs.scipy.org/doc/numpy-1.11.0/reference/c-api.array.html#importing-the-api

I think this can be closed as pyat is working well.
