C++ API

This is the API documentation for the NVIDIA TensorRT library. The NVIDIA TensorRT C++ API allows developers to import, calibrate, generate, and deploy networks using C++. Networks can be imported directly from ONNX. They can also be created programmatically by instantiating individual layers and setting parameters and weights directly.
