%description
XNNPACK is a highly optimized solution for neural network inference on ARM,
x86, WebAssembly, and RISC-V platforms. XNNPACK is not intended for direct
use by deep learning practitioners and researchers; instead it provides
low-level performance primitives for accelerating high-level machine learning
frameworks, such as TensorFlow Lite, TensorFlow.js, PyTorch, ONNX Runtime,
and MediaPipe.
