[yt-users] Error importing yt.mods

[Sam Geen]

Hi,

I've downloaded the latest version of the yt-3.0 branch, and have run 
into some import errors. I've numbered them 1) and 2) below. 1) is 
"ImportError: No module named owls_subfind.api" and 2) is a problem 
locating yt.utilities.

I've deleted the yt egg file and downloaded a clean cloned version, and 
the errors persist. Any ideas?

Thanks!

Sam
