This guide builds from source. For alternatives, refer to https://caffe2.ai/docs/getting-started.html

Note that you might need to uninstall existing Eigen and pybind11 packages due to compile-time dependencies when building from source. For this reason, Caffe2 uses git submodules to reference external packages in the third_party folder. These are downloaded with the --recursive option.

To run the tutorials, download additional source from GitHub.
git clone --recursive https://github.com/caffe2/tutorials.git caffe2_tutorials cd caffe2_tutorials
You'll also need jupyter (formerly ipython) notebooks and matplotlib, which can be installed on MacOS X with
brew install matplotlib --with-python3 pip install jupyter
