How To Get IPython Notebook To Run Python 3?

I am new to Python to bear with me.

I installed Anaconda, works great.

I setup a Python 3 environment following the Anaconda cmd line instructions, works great.

I setup Anaconda's Python 3 environment as Pycharm's interpreter, works great.

I launched the Anaconda "launcher.app" and launched IPython Notebook. However, iPython Notebook is running Python 2 not 3.

Over three hours of Googling later, I cannot figure out how to set IPython Notebook to run Python 3 instead of 2.

You need to launch it from your Python 3 environment. That's easy at a command line (/path/to/env/bin/ipython), but I don't know how to do it from the Anaconda GUI launcher.

Awesome. Thanks. For future searchers, here was the solution: export PATH=/Users/[insertusername]/anaconda/envs/py3k/bin:$PATH ipython notebook

In Anaconda "launcher.app" there is “Environment:” pull down menu.
The default environment is called "root". In order to launch application using another environment, just select the desired environment from the list, to make it active.
