The Jupyter Notebook is a web application that allows you to create and share documents that contain live code, equations, visualizations and explanatory text.
You can also use Jupyter with Python 3:
module load anaconda3/2018.12 start_jupyter
Just load the desired python version first
Keep in mind that CDH 6.1 does not officially support Python 3 yet
You can also try the new Jupyter Lab:
module load anaconda2/2018.12 start_jupyter-lab
