Fine-tune PP-OCRv4 DET Server Model

[lsch0lz]

Hi!
I want to fine-tune the server detection model. Am I right assuming, that this is simply only the teacher model, without any students?
So training with python3 tools/train.py -c configs/det/ch_PP-OCRv4/ch_PP-OCRv4_det_teacher.yml should fine-tune the from you provided server model?
Do I have to use the pre-trained weights LINK anyhow? I see in the config, that there is a different model being used as pretrained_model.

Thanks!

pretrained_model: https://paddleocr.bj.bcebos.com/pretrained/PPHGNet_small_ocr_det.pdparams

In order to finetune the ppocrv4 server model, you can download the pretrained model from this link: https://paddleocr.bj.bcebos.com/PP-OCRv4/chinese/ch_PP-OCRv4_det_server_train.tar
then modify the pretrained_model to the path of the model.
