## 3. Model Training / Evaluation / Prediction
The above DRRG model is trained using the CTW1500 text detection public dataset. For the download of the dataset, please refer to [ocr_datasets](./dataset/ocr_datasets_en.md).
After the data download is complete, please refer to [Text Detection Training Tutorial](./detection_en.md) for training. PaddleOCR has modularized the code structure, so that you only need to **replace the configuration file** to train different detection models.

## 4. Inference and Deployment
<aname="4-1"></a>
### 4.1 Python Inference
Since the model needs to be converted to Numpy data for many times in the forward, DRRG dynamic graph to static graph is not supported.
