That share is mounted on all the nodes. For Python, I use virtualenv's but instead of activating, the path is changed by the Module file. Personally, I find conda doesn't work very well in a shared environment. It's fine on a personal level/ For R, we have resorted to only installing the main point release because we have >700 libraries installed within R and I don't want to reinstall them every time. We do also have packrat installed so researchers can install their own libraries locally as well. Cheers L.
