Hi Sandra
We're running a Galaxy with PBS Pro as jobs scheduler.
I never had any problem with pbs-python however.
Here, for us, the PBS client is installed locally (on the VM that hosts Galaxy).
Are you sure that PBS is well installed ? Are you able to launch a simple PBS
script with the galaxy user ?
Maybe the error you see (xml.etree.ElementTree.ParseError ) is because one XML
config file has an issue.

Objet : [galaxy-dev] pbs-python issues
Hi all,
As a galaxy newbie, I'm struggling to get the pbs-python module working on our
galaxy instance. PBS is installed to a custom location on a shared filesystem
mounted via NFS to our galaxy server, however, installing pbs-python using the
git clone / python venv method in the documentation fails because it can't find
PBS and there does not appear to be any way to define it for pbs-python (I
could be wrong?).

So I went ahead and installed pbs_python from source (which does allow you
define a PBS_PYTHON_INCLUDEDIR environment variable), however, galaxy does not
seem to like this as evidenced by errors during startup. I suspect this has to
do with pbs_python not being installed into the galaxy virtual environment.

I've attempted reinstalls of the git clone / python venv method with the PBS
environment variable to no avail. I was wondering if someone might have any
ideas about working around this roadblock, or may have encountered a similar
module installation issue in the past?
Also, I was hoping to get some ideas/examples of generic job_conf.xml
definitions for PBS clusters? Things like best practices, caveats, etc. My
understanding is that, unless configured otherwise, galaxy will submit jobs as
the galaxy user and that configuring the server to run jobs as end users
themselves is difficult/risky. Just wondering if you guys might have
opinions/thoughts/recommendations about this?
And finally, what would be a good way to test that galaxy is submitting jobs to
the queue properly? Is there some generic test data/procedure to verify that
the galaxy instance is working as expected?
Thanks,
