%description
ONNX Runtime is a cross-platform inference and training machine-learning accelerator.

ONNX Runtime inference can enable faster customer experiences and lower costs, supporting models from deep learning 
frameworks such as PyTorch and TensorFlow/Keras as well as classical machine learning libraries 
such as scikit-learn, LightGBM, XGBoost, etc. 
ONNX Runtime is compatible with different hardware, drivers, and operating systems, and provides optimal performance 
by leveraging hardware accelerators where applicable alongside graph optimizations and transforms.

This package internally uses some of the pacakge listed in https://github.com/microsoft/onnxruntime/blob/rel-%{version}/cmake/deps.txt.
Used package list: date,flatbuffers,google_nsync,googletest,gsl,boost,nlohmann_json,onnx,protobuf,pybind11,re2,safeint,eigen
