I don't know what to do about this. Where is the requirement for collections coming from (it's not amdahl, unless that is indirectly via mpi4py which is it's only dependency).

Ah, it is from https://github.com/carpentries-incubator/hpc-workflows/blob/gh-pages/code/plotcount.py#L8 so that makes me worry less about this. I believe we have a pretty simple use case and we'll need to rewrite that file anyway so I suspect this requirement will disappear.

In general, this is a good idea, we should maintain a requirements.txt
