那量化训练的意义在哪里？
精度不一样，

精度不一样，
@lyuwenyu 都用trt_int8推理，精度不一样在哪里？
另外还是想知道，如何将量化后模型用GPU推理且精度为int8？

@lyuwenyu
你说的是不是准确率不同？但实测下来同样在trt_int8精度下，量化后模型的准确率还不如原始模型
另外终于找到了GPU下修改推理精度的方法，在
https://github.com/PaddlePaddle/Paddle-Inference-Demo/blob/master/c%2B%2B/gpu/gpu_fp16/resnet50_gpu_fp16.cc#L48
但实测下来，只支持float16，不支持int8

应该是量化训练这一阶段没训练好

我很怀疑一般的模型，通过四舍五入以更低精度推理，真的会和专门进行一次量化训练，有很大差别吗？
算了就这样吧
