Thanks for the quick reassurance and the workaround sam. Unfortunately I'm seeing the same thing in a fresh clone so I must have something in my path somewhere that is messing with cython somehow... I'm going to try again in a virtualenv tomorrow, but for now I'll stick to 3.0. -Nathan On Thu, Jan 30, 2014 at 9:10 PM, Sam Skillman <samskillman@gmail.com> wrote:

I've seen the same thing when I do the following:

Install yt-2.x Pull in 3.0 changes Update to 3.0, python setup.py develop Update back to 2.x branch. python setup.py develop

It also may have to do with Cython, as usually in my panic to get back a functioning 2.x i uninstall and reinstall about 10 different versions of cython.

I have *absolutely no idea how this happens*, but the only way I can install 2.x again is from a completely fresh clone, after removing all references to 3.0 in my pythonpath. Super weird. This is the Heisenbug that has popped up from time to time.

You're not crazy. Something else definitely is.

Hi all,

I've suddenly started having issues with cython trying to process grid_traversal.pyx in the yt branch.

See: http://paste.yt-project.org/show/4262/

This might be related to Cython 0.20, as I had that installed initially. That said, I've tried with 0.19 and 0.18, and both fail in the same way.

This is strange, since I'm pretty sure I build 2.7dev sometime last week and I don't think anything has changed.

Is anyone else seeing the same thing?

Thanks!
