Install Ipython / Jupyter in Cygwin for Python 2.7 or Python 3

Install Jupyter Notebook in Cygwin

1. install python3-devel python3-zmq from Cygwin Installer
2. install pip in Cygwin 
3. pip3 install jupyter

Run Jupyter Notebook from Cygwin

Prevent Jupyter from trying to open the notebook in non-graphical, no Javascript Lynx:

jupyter notebook --no-browser

copy the URL given to your Windows web browser and you’ll be using the Cygwin-hosted Jupyter notebook.

Of course, you can use Anaconda Python directly in Windows to do the same thing.
