Web4 Aug 2024 · 用Tensorrt加速有两种思路，一种是构建C++版本的代码，生成engine，然后用C++的TensorRT加速。另一种是用Python版本的加速，Python加速有两种方式，网上基本上所有的方法都是用了C++生成的engine做后端，只用Python来做前端，这里我提供了另外一个用torchtrt加速的版本。 Web10 Apr 2024 · 通过上述这些算法量化时，TensorRT会在优化网络的时候尝试INT8精度，假如某一层在INT8精度下速度优于默认精度（FP32或者FP16）则优先使用INT8。这个时候我们无法控制某一层的精度，因为TensorRT是以速度优化为优先的（很有可能某一层你想让它跑int8结果却是fp32）。
