Caffe2

Caffe2 is a deep learning framework made with expression, speed, and modularity in mind. It is an experimental refactoring of Caffe, and allows a more flexible way to organize computation.

Android and iOS

We use CMake's Android and iOS ports to build native binaries that you can then integrate into your Android or Xcode projects. See scripts/build_android.sh and scripts/build_ios.sh for more details.

For Android, one can also use gradle to build Caffe2 directly with Android Studio. An example project can be found here. Note that you may need to configure Android Studio so that it has the right SDK and NDK versions to build the code.

Raspberry Pi

For Raspbian, run scripts/build_raspbian.sh on the Raspberry Pi.

Tegra X1

To install Caffe2 on NVidia's Tegra X1 platform, simply install the latest system with the NVidia JetPack installer, and then run scripts/build_tegra_x1.sh on the Tegra device.

Python support

To run the tutorials you'll need ipython-notebooks and matplotlib, which can be installed on OS X with:

brew install matplotlib --with-python3
pip install ipython notebook
