<br>
I've had occasion recently also to be adding frontends to be<br>
auto-discovered. The way that frontends work is that they are<br>
self-registering classes. When the class, in this case<br>
ARTIOStaticOutput is defined, the metaclass gets called and this<br>
inserts a reference to the frontend's static output into the known set<br>
of data types. You're likely seeing this in your run on the command<br>
line for plot.<br>
<br>
I would also guess that things aren't being activated correctly. What<br>
happens if you manually import it in your script, above yt.mods, and<br>
print it out? Because printing out a module object will include the<br>
path, this can help us see where thigns might be going wrong.<br>
<br>
import yt.mods; print yt.mods<br>
import yt.frontends.artio.api as artio; print artio<br>
<br></blockquote><div> </div><div style>Eek, got it. Thanks for the debugging tips (and advice below)! print yt.mods yielded the wrong repo path... The issue was that I linked my script between clones. It looks like that link was followed for importing yt.mods, but the rest of yt was activated in the correct path. </div>

And it may also now be the case that if you manually import it, you<br>
can load from it.<br>
<br>
As a point of reference, one thing I have become accustomed to<br>
prefixing all the scripts that absolutely need to run in a particular<br>
clone of yt with something like this at the top of the script:<br>
<br>
import sys<br>
sys.path.insert(0, "/home/mturk/yt/yt-3.0")<br>
<br>
Then you can go on to do stuff like:<br>
<br>
from yt.mods import *<br>
from yt.frontends.sph.api import OWLSStaticOutput<br>
pf = load("snapshot_033/snap_033.0.hdf5")<br>
<br>
Can you have a go at looking into where the modules are coming from,<br>
and let us know? As another quick idea, it may be that if you want to<br>
move back and forth, you can avoid using "develop" at all and manually<br>
set your PYTHONPATH. I keep all of my yt repos in $HOME/yt and I use<br>
this alias to switch between them:<br>
<br>
ppbr()<br>
{<br>
PP="${HOME}/yt/$1/"<br>
if [ ! -d ${PP} ] && echo "${PP} doesn't exist" && return<br>
export PYTHONPATH=${PP}<br>
#echo "PYTHONPATH=${PYTHONPATH}"<br>
export YTPATH=${PP}<br>
}<br>
<br>
It's simple, but it works.<br>
