WebApr 24, 2024 · Here is ONE way: using FP16 (float16) (half-precision point) instead of common used FP32 (float32) (single-precision point), together with proper hardware and software support. FP32 VS FP16 WebJul 20, 2024 · TensorRT is an inference accelerator. First, a network is trained using any framework. After a network is trained, the batch size and precision are fixed (with precision as FP32, FP16, or INT8). The trained model is passed to the TensorRT optimizer, which outputs an optimized runtime also called a plan.
