If you are running galaxy on a cluster, you can do one of two things: 1. install python on every node in your cluster and ensure they are identical. <-- I've had problems with this method 2. use pyenv to create a python environment that gets sourced before you start galaxy and before any galaxy jobs are run. I usually activate it by putting it in .bashrc Iyad Kandalaft Bioinformatics Programmer Microbial Biodiversity Bioinformatics Science & Technology Branch Agriculture & Agri-Food Canada Iyad.Kandalaft@agr.gc.ca | (613) 759-1228 ________________________________ From: igko50@gmail.com [igko50@gmail.com] on behalf of INKozin [i.n.kozin@googlemail.com] Sent: June 14, 2014 6:18 PM To: Kandalaft, Iyad Cc: galaxy-dev@lists.bx.psu.edu Subject: Re: [galaxy-dev] troubleshooting Galaxy with LSF I'm not sure what you mean. I'm not using python virtual env, anaconda etc But I do set all variables which are required to run Galaxy such as DRMAA path, PYTHONPATH. In addition to the default Python 2.6, I also tried Python 2.7 built from source.

While it works fine on the OpenSuse 12.1 box, I'm getting a segfault on RH 6.4. Surprisingly, the job however gets submitted and run successfully.
