机器的环境:Ubuntu, cmake-3.5.1, gcc-5.4.0
按照量化教程 执行成功,但是timeProfile对比后,量化版的前向耗时远高于原始版:

Int8:

8

FP32:

32

请问下,是不是步骤有误,或者其他原因?

Please test on Arm CPU.INT8 is not optimized on x86 platform.

We also found the quantinized model takes 5 times longer than the original model for official mbv2 on ubuntu 19.04.
