<div dir="ltr">Hi Wing,<div><br></div><div>Thanks for the bug report, I'm able to reproduce it over here. The issue seems to be that we incremented the "version" number in the latest enzo release and that has interfered with the logic in yt that is used to detect the version of the output type.</div>
<div><br></div><div>I've created an issue to track this here: <a href="https://bitbucket.org/yt_analysis/yt/issue/881/yt-is-unable-to-read-outputs-created-by">https://bitbucket.org/yt_analysis/yt/issue/881/yt-is-unable-to-read-outputs-created-by</a></div>
<div><br></div><div>Hopefully this will be fixed soon, at which point you'll be able to update and get a working copy of yt.</div><div><br></div><div>Thanks for the bug report!</div><div><br></div><div>-Nathan</div></div>
