Breaking changes in dependencies

[sliptype]

While trying to do a clean install, I noticed that both scipy and numpy have breaking changes and the versions in setup.py are not upper-bounded.

I was able to successfully install by installing the following versions:

scipy =1.2.1
numpy =1.16.2

Thanks for reporting this. It's fixed in the develop branch; I'm just behind in pushing a new release.
