-Table Notes:
+注意事项:
-- Latency: All our models test on `Intel-Xeon-Gold-6148` CPU with MKLDNN by 10 threads and `Qualcomm Snapdragon 865(4xA77+4xA55)` with 4 threads by arm8 and with FP16. In the above table, test CPU latency on Paddle-Inference and testing Mobile latency with `Lite`->[Paddle-Lite](https://github.com/PaddlePaddle/Paddle-Lite).
-- PicoDet is trained on COCO train2017 dataset and evaluated on COCO val2017. And PicoDet used 4 GPUs for training and all checkpoints are trained with default settings and hyperparameters.
-- Benchmark test: When testing the speed benchmark, the post-processing is not included in the exported model, you need to set `-o export.benchmark=True` or manually modify [runtime.yml](https://github.com/PaddlePaddle/PaddleDetection/blob/develop/configs/runtime.yml#L12).
+- 时延测试: 我们所有的模型都在英特尔至强6148的CPU(MKLDNN 10线程)和`骁龙865(4xA77+4xA55)`的ARM CPU上测试(4线程,FP16预测)。上面表格中标有`CPU`的是使用Paddle Inference库测试,标有`Lite`的是使用[Paddle Lite](https://github.com/PaddlePaddle/Paddle-Lite)进行测试。
+- PicoDet在COCO train2017上训练,并且在COCO val2017上进行验证。使用4卡GPU训练,并且上表所有的预训练模型都是通过发布的默认配置训练得到。
+- Benchmark测试:测试速度benchmark性能时,导出模型后处理不包含在网络中,需要设置`-o export.benchmark=True` 或手动修改[runtime.yml](https://github.com/PaddlePaddle/PaddleDetection/blob/develop/configs/runtime.yml#L12)。

-注意事项:
+Table Notes:
-- 时延测试: 我们所有的模型都在英特尔至强6148的CPU(MKLDNN 10线程)和`骁龙865(4xA77+4xA55)`的ARM CPU上测试(4线程,FP16预测)。上面表格中标有`CPU`的是使用Paddle Inference库测试,标有`Lite`的是使用[Paddle Lite](https://github.com/PaddlePaddle/Paddle-Lite)进行测试。
-- PicoDet在COCO train2017上训练,并且在COCO val2017上进行验证。使用4卡GPU训练,并且上表所有的预训练模型都是通过发布的默认配置训练得到。
-- Benchmark测试:测试速度benchmark性能时,导出模型后处理不包含在网络中,需要设置`-o export.benchmark=True` 或手动修改[runtime.yml](https://github.com/PaddlePaddle/PaddleDetection/blob/develop/configs/runtime.yml#L12)。
+- Latency: All our models test on `Intel-Xeon-Gold-6148` CPU with MKLDNN by 10 threads and `Qualcomm Snapdragon 865(4xA77+4xA55)` with 4 threads by arm8 and with FP16. In the above table, test CPU latency on Paddle-Inference and testing Mobile latency with `Lite`->[Paddle-Lite](https://github.com/PaddlePaddle/Paddle-Lite).
+- PicoDet is trained on COCO train2017 dataset and evaluated on COCO val2017. And PicoDet used 4 GPUs for training and all checkpoints are trained with default settings and hyperparameters.
+- Benchmark test: When testing the speed benchmark, the post-processing is not included in the exported model, you need to set `-o export.benchmark=True` or manually modify [runtime.yml](https://github.com/PaddlePaddle/PaddleDetection/blob/develop/configs/runtime.yml#L12).
