Hi Nate,

I tried to get this to work, but it is not getting rid of the error.  I was able to symlink the platform dependent lib-dynload libraries to a recognized directory, which removed the error telling me _hashlib was not found.  Now, I’m just left with:

galaxy.jobs.output_checker DEBUG 2018-01-28 21:50:36,883 Tool produced standard error failing job - [Could not find platform dependent libraries <exec_prefix>

Consider setting $PYTHONHOME to <prefix>[:<exec_prefix>]

]

Maybe, as Cao suggested, I should just be installing a common version in the shared directory between the two filesystems.  The job is correctly being scheduled and completes, metadata is just not written.  I’m certainly open to any additional ideas.

Thanks,

John

Subject: Re: [galaxy-dev] Cluster Install Path Errors

I think this error most commonly occurs when a virtualenv is used with a different python than the one it was created with. Is the cluster also running Ubuntu 14.04? If not, you can create a separate virtualenv for running tools using the instructions at:

https://docs.galaxyproject.org/en/master/admin/framework_dependencies.html#managing-dependencies-manually

Once created, your tools can use it by setting `<param id="GALAXY_VIRTUAL_ENV">/path/to/venv</param>` on the destination in job_conf.xml

You can try to install:

Thanks for the response Peter.  I currently have this instance installed on a lustre fs, that is visible on an Ubuntu 14.04 vm.  So, there very well may be mismatches between directories on the VM, and those on the lustre cluster.  This would mean the python installation on the VM needs to exactly match that which is on the cluster?  What else will need to match to ensure success?

Thanks,
John

    I *think* this is a problem with your copy of Python 2.7 and a
    standard library (hashlib) normally present. Do you know how this
    Python was installed? If it was compiled from source, then it may have
    been missing a few dependencies, and thus you have ended up with
    missing a few normally present Python modules.
