Caffe (Convolutional Architecture for Fast Feature Embedding) is an open-source deep learning framework originally developed by Yangqing Jia from the University of California, Berkeley. In April 2017, Facebook released Caffe2, which includes new features such as Recurrent Neural Networks (RNNs). At the end of March 2018, Caffe2 was merged into PyTorch.
