MM_DNN在4w+样本上预测， 编译时需打开：-DWITH_INFERENCE_API_TEST=ON 运行命令：

cd build
./paddle/fluid/inference/tests/api/test_analyzer_mm_dnn --infer_model=third_party/inference_demo/mm_dnn/model/ --infer_data=third_party/inference_demo/mm_dnn/data.txt --gtest_filter=Analyzer_MM_DNN.profile --test_all_data

环境：V100，镜像：paddlepaddle/paddle_manylinux_devel:cuda9.0_cudnn7 CPU可以跑通，GPU报错： GPU 需要修改下 paddle/fluid/inference/tests/api/analyzer_mm_dnn_tester.cc
