How to use recent text detectors with RapidOCR?

[halqadasi]

If I want to use one of the text detectors in this link instead of DB algorithm (default). I use paddleocr_convert but it throws an error. This is an example to convert SAST algorithm to onnex:

from paddleocr_convert import PaddleOCRModelConvert

converter = PaddleOCRModelConvert()
save_dir = 'models'
url = 'https://paddleocr.bj.bcebos.com/dygraph_v2.0/en/det_r50_vd_sast_icdar15_v2.0_train.tar'
converter(url, save_dir)

The error log:

---------------------------------------------------------------------------
IndexError                                Traceback (most recent call last)
File ~\anaconda3\lib\site-packages\paddleocr_convert\main.py:49, in PaddleOCRModelConvert.__call__(self, model_path, save_dir, txt_path, is_del_raw)
     48 try:
---> 49     self.change_to_dynamic(save_onnx_path)
     50 except Exception as e:

File ~\anaconda3\lib\site-packages\paddleocr_convert\main.py:113, in PaddleOCRModelConvert.change_to_dynamic(self, onnx_path)
    112 onnx_model = onnx.load_model(onnx_path)
--> 113 dim_shapes = onnx_model.graph.input[0].type.tensor_type.shape.ListFields()[0][1]
    115 dynamic_name = 'DynamicDimension'

IndexError: list index out of range

The above exception was the direct cause of the following exception:

ConvertError                              Traceback (most recent call last)

----> 7 converter(url, save_dir)

File ~\anaconda3\lib\site-packages\paddleocr_convert\main.py:51, in PaddleOCRModelConvert.__call__(self, model_path, save_dir, txt_path, is_del_raw)
     49     self.change_to_dynamic(save_onnx_path)
     50 except Exception as e:
---> 51     raise ConvertError(
     52         'change the model to dynamic meets error.') from e
     54 if is_rec:
     55     txt_path = self.get_file_path(txt_path, '.')

ConvertError: change the model to dynamic meets error.

Could you please tell me how I can use different text detection algorithms instead of the specified ones in this page here.

• Currently, the paddleocr_convert package only supports the inference model to convert to onnx format.
• Other algorithm model format conversion is not supported.
