Installation with conda

To install the latest Gammapy stable version as well as the most common optional dependencies for Gammapy, first install Anaconda and then run these commands:

conda config --add channels conda-forge --add channels sherpa
conda install gammapy naima sherpa \
    scipy matplotlib ipython-notebook \
    cython click

We strongly recommend that you install the optional dependencies of Gammapy to have the full functionality available:

conda install scikit-image aplpy photutils reproject iminuit

To update to the latest version:

conda update --all
conda update gammapy

Overall conda is a great cross-platform package manager, you can quickly learn how to use it by reading the docs here.
