Thanks for your help, Marius. Turns out what I need is this: <destination id="uge_default" runner="uge"> <env id="GALAXY_VIRTUAL_ENV">None</env> </destination> Otherwise the job script that is written by Galaxy will activate the virtual env on the worker node, which is not what I want to happen.

Are you perhaps using a supervisor setup where you are setting the PATH ? In that case you can remove /phengs/hpc_storage/home/galaxy_hpc/galaxy-dist/.venv/bin from the PATH. If you're referencing python you can directly use the path to /phengs/hpc_storage/home/galaxy_hpc/galaxy-dist/.venv/bin/python.
Best, Marius

Hi Marius
This is very useful, but not quite there.
I use in my job_conf.xml
<destination id="uge_default" runner="uge"> <env id="PATH">/this/is/a/test</env> </destination>
and I end up with this
PATH=/phengs/hpc_storage/home/galaxy_hpc/galaxy-dist/.venv/bin:/this/is/a/test
Any idea where that came from?
Thanks Ulf

Hi Ulf,
you can set a virtualenv to be used in your job_conf.xml file. The following line would go into the `<destination></destination>` tag: `<env file="path_to_venv/bin/activate" />`
Best, Marius

Hi again
Update, sorry for spamming:
It is not ALL jobs that fail. Only the ones that get dispatched to our Grid Engine cluster (so nearly all).
The reason appears to be that the path to the Python binary is added to the PATH variable when the job arrives on the worker node:
[galaxy_hpc@hpc1node25 galaxy-dist]$ export
PATH=/home/galaxy_hpc/galaxy-dist/.venv/bin:/tmp/5000354.1.researchmid.q:/usr/local/bin:/bin:/usr/bin [galaxy_hpc@hpc1node25 galaxy-dist]$ python Could not find platform dependent libraries <exec_prefix> Consider setting $PYTHONHOME to <prefix>[:<exec_prefix>] Python 2.7.6 (default, Oct 25 2017, 12:28:23) [GCC 4.4.7 20120313 (Red Hat 4.4.7-4)] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> import json Traceback (most recent call last): File "<stdin>", line 1, in <module> ImportError: No module named json
This is the wrong python to be running there. It should just go with the one in /usr/bin. If I change PATH, it works fine:
[galaxy_hpc@hpc1node25 galaxy-dist]$ export
PATH=/tmp/5000354.1.researchmid.q:/usr/local/bin:/bin:/usr/bin[galaxy_hpc@hpc1node25 galaxy-dist]$ python Python 2.6.6 (r266:84292, Aug 9 2016, 06:11:56) [GCC 4.4.7 20120313 (Red Hat 4.4.7-17)] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> import json >>>
Does anyone have an idea how I can stop this from happening? Where is the PATH set before submitting the job?
Thanks Ulf

Hi all
After running the recommended update I am now on branch 17.09. As part of the update I set up a new virtual env running an additional python 2.7.6. My previous virtual env was running 2.6.6 which is a system requirement for Centos 6.
All dependencies were installed and Galaxy starts fine, but no tools run. The error is always a variation of this:
Could not find platform dependent libraries <exec_prefix> Consider setting $PYTHONHOME to <prefix>[:<exec_prefix>] Traceback (most recent call last): File
"galaxy-dist/database/jobs_directory/000/418/418014/set_metadata_4LcsZv.py", line 1, in <module> from galaxy_ext.metadata.set_metadata import set_metadata; set_metadata() File "galaxy-dist/lib/galaxy_ext/metadata/set_metadata.py", line 19, in <module> import json ImportError: No module named json
I put some debug output at the top of set_metadata.py and it is indeed running the correct python version from the virtual env. Needless to say I can import json just fine using that python version. Any ideas?
Any help is greatly appreciated.
Thanks Ulf
