# Add plugins to the BackBone network
# Add plugins to the Backbone network
MMYOLO supports adding plug-ins such as none_local and dropout after different stages of BackBone. Users can directly manage plug-ins by modifying the plugins parameter of backbone in config. For example, add GeneralizedAttention plug-ins for `YOLOv5`. The configuration files are as follows:

)
```
## Use backbone network implemented in other OpenMMLab repositories
The model registry in MMYOLO, MMDetection, MMClassification, and MMSegmentation all inherit from the root registry in MMEngine in the OpenMMLab 2.0 system, allowing these repositories to directly use modules already implemented by each other. Therefore, in MMYOLO, users can use backbone networks from MMDetection and MMClassification without reimplementation.
```{note}
1. When using other backbone networks, you need to ensure that the output channels of the backbone network match the input channels of the neck network.
2. The configuration files given below only ensure that the training will work correctly, and their training performance may not be optimal. Because some backbones require specific learning rates, optimizers, and other hyperparameters. Related contents will be added in the "Training Tips" section later.
```

)
```
## 跨库使用主干网络
OpenMMLab 2.0 体系中 MMYOLO、MMDetection、MMClassification、MMSegmentation 中的模型注册表都继承自 MMEngine 中的根注册表,允许这些 OpenMMLab 开源库直接使用彼此已经实现的模块。 因此用户可以在 MMYOLO 中使用来自 MMDetection、MMClassification 的主干网络,而无需重新实现。
```{note}
1. 使用其他主干网络时,你需要保证主干网络的输出通道与 Neck 的输入通道相匹配。
2. 下面给出的配置文件,仅能确保训练可以正确运行,直接训练性能可能不是最优的。因为某些 backbone 需要配套特定的学习率、优化器等超参数。后续会在“训练技巧章节”补充训练调优相关内容。
