# 给主干网络增加插件
|
||
|
|
||
|
|
MMYOLO 支持在 Backbone 的不同 Stage 后增加如 `none_local`、`dropblock` 等插件，用户可以直接通过修改 config 文件中 `backbone` 的 `plugins`参数来实现对插件的管理。例如为 `YOLOv5` 增加`GeneralizedAttention` 插件，其配置文件如下：
|
||
|
|
|
||
|
|
```python
|
||
|
|
_base_ = './yolov5_s-v61_syncbn_8xb16-300e_coco.py'
|
||
|
|
|
||
|
|
model = dict(
|
||
|
|
backbone=dict(
|
||
|
|
plugins=[
|
||
|
|
dict(
|
||
|
|
cfg=dict(
|
||
|
|
type='GeneralizedAttention',
|
||
|
|
spatial_range=-1,
|
||
|
|
num_heads=8,
|
||
|
|
attention_type='0011',
|
||
|
|
kv_stride=2),
|
||
|
|
stages=(False, False, True, True))
|
||
|
|
]))
|
||
|
|
```
|
||
|
|
|
||
|
|
`cfg` 参数表示插件的具体配置， `stages` 参数表示是否在 backbone 对应的 stage 后面增加插件，长度需要和 backbone 的 stage 数量相同。
|
