I think those are only needed for the data generation? So would just force unecessary libs on the majority who just want the client?

Adds more weight to idea that we should split the data into own package though as per #64

[holtgrewe]

That is correct. I agree, an alternative option would be to have a build "feature" in the package, enabled by the availability of these packages.

I took your changes to setup and added them to a requirements.txt in the generate data directory - thanks for collecting what we needed to run things

I think the package optional features would only make sense if we distributed the generate scripts with the package which I dont' really want to do
