requirements.txt

[genedan]

What is the requirements.txt file used for? I was wondering because it seems like we (John, Kenneth, me) use conda environments for development. But I do see that requirements.txt gets updated every now and then, so I was curious if there was a use case that I was unaware of.

Reason being, there are a bunch of package imports throughout the code that aren't listed in the requirements file, but I thought I should ask about what people used it for or the reason why some packages (like numpy) are left out before I went gung-ho on adding all of them in there.

setup.py uses requirements.txt to determine dependencies for the build hosted on pypi. If we're using numpy directly, we should probably say so. I think its missing because pandas had historically included numpy as a dependency automatically.
