The code in the tutorial has been written using Python 3; though most of it may also work with Python 2.7.

We strongly recommend using the Anaconda Python distribution. You can install either the full anaconda distribution (very extensive, but large) or miniconda (much smaller, only essential packages).

There are download instructions below for installation using pip, which should work with any Python distribution.

The steps below will get you a working environment.

conda create -n widgets-tutorial notebook=5.0 numpy python=3.6 scikit-image scipy

# Mac/Linux:
source activate widgets-tutorial

# Windows:
activate widgets-tutorial

# Install widgets from conda-forge, which has ipywidgets 7.0
conda install -c conda-forge ipywidgets=7.0 traittypes

# Create a kernel for this environment
ipython kernel install --name widgets-tutorial --display-name widgets-tutorial --sys-prefix

If you are not using the anaconda python distribution, please use the instructions below.

pip install ipywidgets
jupyter nbextension enable --sys-prefix --py widgetsnbextension
