 **注意:**
-  - YOLOX模型训练使用COCO train2017作为训练集，YOLOXv2表示使用与YOLOv5 releases v6.0之后版本相同的主干网络，YOLOX-crn表示使用与PPYOLOE相同的主干网络CSPResNet，YOLOX-ConvNeXt表示使用ConvNeXt作为主干网络；
+  - YOLOX模型训练使用COCO train2017作为训练集，YOLOX-cdn表示使用与YOLOv5 releases v6.0之后版本相同的主干网络，YOLOX-crn表示使用与PPYOLOE相同的主干网络CSPResNet，YOLOX-ConvNeXt表示使用ConvNeXt作为主干网络；
   - YOLOX模型训练过程中默认使用8 GPUs进行混合精度训练，默认每卡batch_size为8，默认lr为0.01为8卡总batch_size=64的设置，如果**GPU卡数**或者每卡**batch size**发生了改变，你需要按照公式 **lr<sub>new</sub> = lr<sub>default</sub> * (batch_size<sub>new</sub> * GPU_number<sub>new</sub>) / (batch_size<sub>default</sub> * GPU_number<sub>default</sub>)** 调整学习率；
   - 为保持高mAP的同时提高推理速度，可以将[yolox_cspdarknet.yml](_base_/yolox_cspdarknet.yml)中的`nms_top_k`修改为`1000`，将`keep_top_k`修改为`100`，将`score_threshold`修改为`0.01`，mAP会下降约0.1~0.2%；
   - 为快速的demo演示效果，可以将[yolox_cspdarknet.yml](_base_/yolox_cspdarknet.yml)中的`score_threshold`修改为`0.25`，将`nms_threshold`修改为`0.45`，但mAP会下降较多；
