Hi Everyone,<br>
<br>
I'm having trouble using yt in parallel. I'm getting an error message;<br>
AttributeError: 'module' object has no attribute 'rootLogger'<br>
<br>
I'm running this simple test script<br>
#test_script.py<br>
import yt<br>
yt.enable_parallelism(suppress_logging=True, communicator=None)<br>
# Load the dataset<br>
filename='Data/enzo_cosmology_plus/DD0046/DD0046'<br>
ds=yt.load(filename)<br>
v,c=ds.find_max("density")<br>
print v,c<br>
<br>
this runs fine when just executing python test_script.py, but if I do<br>
mpirun -np 4 python test_script.py<br>
I get the following<br>
<br>

Any thoughts would be greatly appreciated.<br>

Hi Ari,<br>
<br>
Thanks for the report! This is a genuine bug, due to a pull request that<br>
was merged just a few days ago that removed the rootLogger.<br>
<br>
If you update to the change before the pull request was merged (changeset<br>
hash bca4a05), this issue should go away. Let us know if you need help<br>
updating to the old version.<br>
<br>
I've opened an issue to track this:<br>
<a href="https://bitbucket.org/yt_analysis/yt/issue/956/enable_parallelism-dies-due-to-missing" target="_blank">https://bitbucket.org/yt_analysis/yt/issue/956/enable_parallelism-dies-due-to-missing</a><br>
<br>
If you have a bitbucket account, you can watch the issue to get e-mail<br>
updates.<br>
<br>
Hopefully we should have this fixed soon.<br>
<br>
-Nathan<br>
