[yt-dev] Issue #889: yt update --all fails when updating from numpy 1.7 to 1.8 on some systems (yt_analysis/yt)

New issue 889: yt update --all fails when updating from numpy 1.7 to 1.8 on some systems https://bitbucket.org/yt_analysis/yt/issue/889/yt-update-all-fails-when-upda... Cameron Hummels: Since the addition of Pull Request #1168, which updates the version of numpy from 1.7 to 1.8, some attempts to update yt's dependencies in place fail with this error: ``` #!python ImportError: cannot import name multiarray ``` See here for full traceback: http://paste.yt-project.org/show/5077/ This appears to be a problem on mac systems and TACC Stampede, and perhaps others. One solution to this is to wipe yt and reinstall from the install script, but a different solution is desired.
