New issue 938: Units error with creating light ray from single dataset https://bitbucket.org/yt_analysis/yt/issue/938/units-error-with-creating-lig... Devin Silvia: When I try to generated a light ray from a single dataset, I get a YTUfuncUnitError message. Here's the script: http://paste.yt-project.org/show/5197/ And here is the output: http://paste.yt-project.org/show/5198/ I'd try to troubleshoot this a bit, but all of my attempts just seemed to push the error off to a different piece of the code base, so I think perhaps something more fundamental might be the culprit.
