My question is not really about Kwant, but about how to install Jupyter. I have a 64-bit operating system with Windows 8. I have successfully installed Python 3.4. I want to install Jupyter notebook, but I am not sure what files I need from Cristoph Gohlke's website ( http://www.lfd.uci.edu/~gohlke/pythonlibs/). When I eventually get the required files, what is the installation procedure? Can any one advise?
