Description

在跑通act示例项目过程中发现CPU量化推理精度下降比较严重，发现是在测试的时候比量化训练多量化了pool2d以及elementwise_mul两个op，去掉之后推理精度恢复正常水平。下面是实验结果，都设置了benchmark=True：

原模型fp32推理 原模型fp32+mkldnn加速 量化模型int8推理（量化conv2d,depthwise_conv2d） 量化模型int8推理（量化conv2d,depthwise_conv2d,elementwise_mul） 量化模型int8推理（量化conv2d,depthwise_conv2d,elementwise_mul,pool2d）
