See Recipes for examples of building virtual environments for specific packages.

If you are going to follow the instructions for creating an Anaconda virtual environment on DARWIN consider using a slight modification to the documentation provided by each software package and use VALET to load the proper version of Anaconda for Python 2 or Python 3, specify a path in your home ($HOME) or workgroup ($WORKDIR) directory not in the system path for Anaconda, and also ignore the warnings to update conda as it is building your virtual environment.

See the example below which creates a virtual Anaconda environment based on Python 3 for FEniCS called fenicsproject in the traine home directory and installs all the fenics packages and mshr. Once the environment is created, then a simple interactive test is done on a compute node via the devel partition to verify the new fenicsproject Anaconda environment is working properly.

Examples documented as recipes to be used for specific installations including using a workgroup directory as well as creating VALET packages for these environments and job scripts setup for batch runs, but can also perhaps help others in solving similar installation dilemmas.
