How to use inference model?

[noki1928]

Can you help me, I don't understand how to use the model I retrained on my data. If I use the Python API, an error occurs. Му inferens dir have inference.json, inference.yml and inference.pdiparams

ocr = PaddleOCR(text_recognition_model_dir='rec_plate_nrtr')

Hello, the inference logic of PaddleOCR 3.0 is tied to the model names.
NRTR does not appear to be in the supported list of PaddleOCR 3.0.
If its pre-processing and post-processing logic are consistent with PP-OCRv5_server_rec, you can directly change the model_name: to PP-OCRv5_server_rec.
