Permission Denied (publickey)

[Zleander]

When trying to clone probnum within the pip install, I'm running into Permission Denied (publickey)

I just copied the entire command line output here, I hope it's somewhat readable

Thanks for the detailed bug report!

TL;DR

Try to clone the repository again. The bug hopefully should be fixed now. If not, feel free to reopen.

Detailed Explanation

This happened because itergp depends on a not-yet-released version of probnum that is only available as a GitHub repository. Internally the package tries to do

pip install git+ssh://git@github.com/marvinpfoertner/probnum.git@ad-prototype

So this command above should produce a similar error message. Github doesn't allow installs via pip in this manner without having deposited a public key in your Github profile. I replaced the installation in the dependencies with

pip install git+https://github.com/marvinpfoertner/probnum.git@ad-prototype

which should be possible for anybody.
