 ## 1. How to generate INT8 MKL-DNN QAT model
 You can refer to the unit test in [test_quantization_mkldnn_pass.py](test_quantization_mkldnn_pass.py). Users firstly use PaddleSlim quantization strategy to get a saved fake QAT model by [QuantizationFreezePass](https://github.com/PaddlePaddle/models/tree/develop/PaddleSlim/quant_low_level_api), then use the `QatInt8MkldnnPass` (from QAT1.0 MKL-DNN) to get a graph which can be run with MKL-DNN INT8 kernel. In Paddle Release 1.6, this pass supports `conv2d` and `depthwise_conv2d` ops with channel-wise quantization for weights. Apart from it, another pass called `Qat2Int8MkldnnPass` (from QAT2.0 MKL-DNN) is available for use. In Release 1.6, this pass additionally supports `pool2d` op and allows users to transform their QAT model into a highly performance-optimized INT8 model that is ran using INT8 MKL-DNN kernels. In Release 1.7, a support for `fc`, `reshape2` and `transpose2` ops was added to the pass.

 You can run the following commands to download ResNet50 model. The exemplary code snippet provided below downloads a ResNet50 QAT model. The reason for having two different versions of the same model originates from having two different QAT training strategies: One for an non-optimized and second for an optimized graph transform which correspond to QAT1.0 and QAT2.0 respectively.

 ### Commands to reproduce benchmark
 
-#### Image classification
 You can use the `qat_int8_image_classification_comparison.py` script to reproduce the accuracy result on ResNet50. The difference between commands usedin the QAT1.0 MKL-DNN and QAT2.0 MKL-DNN is that for QAT2.0 MKL-DNN two additional options are required: the `--qat2` option to enable QAT2.0 MKL-DNN, and the `--quantized_ops` option with a comma-separated list of operators to be quantized. To perform the QAT2.0 MKL-DNN performance test, the environment variable `OMP_NUM_THREADS=1` and `--batch_size=1` option should be set.
