Hi, Since some time ago I wanted to look at how difficult is to get non python software installed inside an anaconda environment and this looked like a good excuse to test it so I did a quick test to get Easybuil+Lmod inside conda. In case anyone want to test it, you can try this:
$> wget -O /tmp/Miniconda2-latest-Linux-x86_64.sh https://repo.continuum.io/miniconda/Miniconda2-latest-Linux-x86_64.sh $> bash /tmp/Miniconda2-latest-Linux-x86_64.sh -b -f $> export PATH=~/miniconda2/bin:$PATH $> conda install -c pescobar lmod=6.5.12 $> pip install easybuild $> source ~/miniconda2/lmod/lmod/init/bash $> eb --modules-tool=Lmod foss-2016a.eb -r --dry-run Following these steps I could get EasyBuild+Lmod running in a vanilla centos7 installation quite easily. I think it should also work in any other linux distribution, no matter which are the installed packages from the OS repos. Personally I like this concept of running easybuild in a self-contained environment with fixed python version and python libraries and even extra non-python dependencies. IMHO, this would simplify the development and testing of easybuild and would make easier to plan the migration to python3. Also developers wouldn't need to worry if the user are going to deploy easybuild in centos6 (python2.6), centos7 (python2.7) or any other distro because easybuild would provide its own well tested python version + dependencies. Still this allows anyone to use a different approach if they prefer like using system's python or a centrally installed Lmod or environment modules (e.g. for a production deployment I would still use an independent Lmod installation). In any case, as I said, this is just an idea/suggestion so the main developers evaluate it. How easybuild is distributed now works fine for me and I also have the choice to use conda or not. regards, Pablo. 2016-09-19 2:44 GMT+02:00 Christopher Samuel <[email protected]>: > On 16/09/16 20:15, Pablo Escobar Lopez wrote: > > > I remember we have commented in some hackathon (while having some beers > > I think) about the possibility of distributing easybuild as a > > self-contained app. Using something like mini-conda > > (http://conda.pydata.org/miniconda.html) with easybuild already > > installed on top of hit could do the trick.
