I'm modifying an extension written with the c-api to have a datatype of quaternions <https://github.com/moble/numpy_quaternion>, with one of the goals being python 3 support. It works nicely in python 2.7, but for python 3.x gives an error that I can't find anywhere on the google. The directory looks like this:
.../site-packages/ quaternion/ __init__.py numpy_quaternion.so __init__.py contains a line like this: from .numpy_quaternion import quaternion But when it hits that line, python 3 throws its hands up in disgust: > python -c 'import quaternion' Traceback (most recent call last): File "<string>", line 1, in <module> File "/Users/mynamehere/.continuum/anaconda/envs/py3k/lib/python3.4/site-packages/quaternion/__init__.py", line 3, in <module> from .numpy_quaternion import quaternion TypeError: __import__() argument 1 must be str, not bytes The only thing before that line is `import numpy as np`, which typically works just fine. Obviously, I'm using python3.4 to compile and (attempt to) import (with a conda environment), so it's not something as dumb as using the wrong python. Also, this is the result for both me on my laptop and Travis-CI <https://travis-ci.org/moble/numpy_quaternion>, so it doesn't seem to be anything peculiar to my installation. I've posted this question on stackoverflow, but haven't gotten much interest; the only responder suggested I ask here instead. Any ideas what's going wrong, or where I can go from here?
