[gamegrd]

Hi Everyone
I got an error when convert the Multilingual Detection Model

BASE INFO

model: ml_PP-OCRv3_det
config: ch_PP-OCRv3_det_cml.yml

command

python3 ./converter/ch_ppocr_v3_det_converter.py --src_model_path ./downloads/Multilingual_PP-OCRv3_det_distill_train

ERROR

During handling of the above exception, another exception occurred:

Thank you guys.
