It's not noise. This does appear to be a bug.

_pyx_kp_29 is never given a value in the generated code so the from_list is
invalid. I am guessing that the "as" is fooling the code generator into
thinking
that there is a from_list.
If that gets fixed, there's more stuff that's broken. The module that gets
returned from __Pyx_Import() as __pyx_2 will be numpy, not numpy.random, so
there must be one or more PyObject_GetAttr()s to get the actual module that
should be assigned to the name "rn".
