Problem when using deepARG in a container with the Theano package: IOError: [Errno 13] Permission denied: '/usr/local/lib/python2.7/site-packages/Theano-0.8.2-py2.7.egg-info/PKG-INFO'
This problem has already been reported and closed in this issue: nf-core/funcscan#23 but there's no clear explanation of how they solved the problem, so I have restarted the discussion to try to get more information.

Just so it doesn't get lost in the closed funcscan thread:

We ended up mounting a dummy file (the bash binary of the execution node) but with the name PKG_INFO:

https://github.com/nf-core/funcscan/blob/master/modules%2Fnf-core%2Fdeeparg%2Fpredict%2Fmain.nf#L10-L18

Also I see lower down in the script execution that we also make a directory for theanos which you may also have to do for cases of singularity (if you use that)

    # Theano needs a writable space and uses the home directory by default,
    # but the latter is not always writable, for instance when Singularity
    # is run in --no-home mode
    mkdir -p theano
    export THEANO_FLAGS="base_compiledir=\$PWD/theano"

deeparg predict <...>

I hope that helps/works for you!
