en_PP-OCRv3_rec convert/inference error

[gliufetch]

all this is about en_paddleOcr_v3_rec model:

1. convert model (https://paddleocr.bj.bcebos.com/PP-OCRv3/english/en_PP-OCRv3_rec_train.tar)

(.venv) ➜  PaddleOCR2Pytorch git:(test) ✗ python3 ./converter/multilingual_ppocr_v3_rec_converter.py --src_model_path en_PP-OCRv3_rec_train
out_channels:  97
<class 'dict'> {}
{'fc_decay': 2e-05, 'in_channels': 64}
model is loaded.
en_PP-OCRv3_rec_train/best_accuracy
out: 40.0 0.010309278 0.9644629 2.816156e-07
model is saved: en_ptocr_v3_rec_infer.pth
done.

Question 1, which converter.py should be used when converting en_PP-OCRv3_rec_train model, multilingual_ppocr_v3_rec_converter.py or just ch_ppocr_v3_rec_converter.py?

2. inference

(.venv) ➜  PaddleOCR2Pytorch git:(test) ✗ python3 ./tools/infer/predict_rec.py --rec_model_path en_ptocr_v3_rec_infer.pth --rec_image_shape 3,48,320 --image_dir ./doc/imgs_words/en/word_1.png  --rec_yaml_path en_PP-OCRv3_rec_v2.5.yml  --rec_char_dict_path en_dict.txt  --image_dir ./doc/imgs_words/en/word_1.png

Question 1: is it because (https://github.com/PaddlePaddle/PaddleOCR/blob/release/2.5/configs/rec/PP-OCRv3/en_PP-OCRv3_rec.yml)

  Head:
    name: MultiHead

for en_ppocrv3_rec?

Question 2: does PaddleOCR2Pytorch support english PaddleOcrV3 rec model that has SVTR_LCNet algorithm (like the one in release 2.7)

Architecture:
  model_type: rec
  algorithm: SVTR_LCNet
  for en_ppocrv3_rec?

[gliufetch]

figured it out,

1. model conversion should use ./converter/multilingual_ppocr_v3_rec_converter.py to convert the en recognition model

2. the yml file is not correct when doing prediction, should use https://github.com/frotms/PaddleOCR2Pytorch/blob/main/configs/rec/PP-OCRv3/en_PP-OCRv3_rec.yml for prediction. (this file is different from the 'default' one in paddleocr.

Thank you for the work!
