## 权重
以下是可用于[推理](user_guides/inference.md)的权重列表。

为了便于使用，有的权重可能会存在多个较短的别名，这在表格中将用“/”分隔。

例如，表格中展示的 `DB_r18 / dbnet_resnet18_fpnc_1200e_icdar2015` 表示您可以使用
`DB_r18` 或 `dbnet_resnet18_fpnc_1200e_icdar2015` 来初始化推理器：

```python
>>> from mmocr.apis import TextDetInferencer
>>> inferencer = TextDetInferencer(model='DB_r18')
>>> # 等价于
>>> inferencer = TextDetInferencer(model='dbnet_resnet18_fpnc_1200e_icdar2015')
```

{weight_list}
