how to use another model

[younes-zeboudj]

I tried to get the models from

https://github.com/PaddlePaddle/PaddleOCR/blob/release/2.7/doc/doc_ch/models_list.md

(the "high" accurancy models)

and converted them to 'onnx' format using 'paddle2onnx'

paddle2onnx --model_dir model_dir \
            --model_filename inference.pdmodel \
            --params_filename inference.pdiparams \
            --save_file model.onnx

And used them as:

ocr = await Ocr.create({
    models:{
      detectionPath: path.resolve(__dirname,'assets', 'ch_PP-OCRv4_det_server_infer.onnx'),
      recognitionPath: path.resolve(__dirname,'assets', 'ch_PP-OCRv4_rec_server_infer.onnx'),
      dictionaryPath:  path.resolve(__dirname,'assets', 'chars.txt'),
    }
  });

But the recognition is not working. If I remove them and use the defaults, it works again.
