Additional information: I just tried installing that py3k branch on a
Snow Leopard machine at work, using the python provided by MacPorts.
In this case, I'm getting:
>>> import h5py
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File
"/Users/darren/.local/lib/python3.1/site-packages/h5py-1.3.1.dev-py3.1-macosx-10.6-x86_64.egg/h5py/__init__.py",
line 34, in <module>
from . import h5, h5a, h5d, h5f, h5fd, h5g, h5l, h5o, h5i, h5p,
h5r, h5s, h5t, h5z
File "h5t.pxd", line 17, in init h5py.h5a (h5py/h5a.c:5248)
File "h5p.pxd", line 23, in init h5py.h5t (h5py/h5t.c:16481)
File "h5t.pxd", line 17, in init h5py.h5p (h5py/h5p.c:9297)
ImportError: No module named h5t
Does python-3 have circular import issues that were not present in python-2?
