 - run_mode：paddle代表使用AnalysisPredictor，精度float32来推理，其他参数指用AnalysisPredictor，TensorRT不同精度来推理。
 - 如果安装的PaddlePaddle不支持基于TensorRT进行预测，需要自行编译，详细可参考[预测库编译教程](https://paddleinference.paddlepaddle.org.cn/user_guides/source_compile.html)。
 - --run_benchmark如果设置为True，则需要安装依赖`pip install pynvml psutil GPUtil`。
+- 如果需要使用导出模型在coco数据集上进行评估，请在推理时添加`--save_results`和`--use_coco_category`参数用以保存coco评估所需要的json文件
