And just for reference, when Greg and John refer to "installing yt as usual" (after switching to the desired changeset in mercurial), they mean, go to the yt-hg directory (e.g. yt-i386/src/yt-hg or yt-x86_64/src/yt-hg) and then type:

python setup.py develop

This should set you up to go. Good luck!

Mercurial contains all of the past changes to yt. In your yt directory, go into src/yt-hg and then type 'hg tags' to list all of the tagged changsets. You can update to any of theses (e.g., 'hg update yt-2.5') and then install using the setup.py script in that directory.

Hi everyone,

I recently updated the yt, then realized there is a license issue with HEALPix in the new version... Is there a way that I can reverse back to my previous version (yt2.5)?

Thanks!
Yong
