+NNPACK aims to provide high-performance implementations of convnet layers for
+multi-core CPUs.

+NNPACK is not intended to be directly used by machine learning researchers;
+instead it provides low-level performance primitives leveraged in leading deep
+learning frameworks, such as PyTorch, Caffe2, MXNet, tiny-dnn, Caffe, Torch,
+and Darknet.")
