Is the OCR evaluation model (ster\crnn) and tatt end-to-end?

Is the OCR evaluation model (ster\crnn) and tatt end-to-end ? OR first use SR model to output results, and then input OCR?
just like the code below：
def getitem(self, index):
...
...
label_str = str_filt(word, self.voc_type)
return img_HR, img_lr, img_HRy, img_lry, label_str

Does “label_str” participate in the training of the whole model？

@HansonnnCheung Not really, TATT follows the settings in the TPGSR, i.e., the label_str is not used in training.

Thank you for your answer. Where did the “teaching_loss” come from during the training. Is "TEXT_Prior" generated by an OCR model? @mjq11302010044

In addition, if "lable_str" does not participate in training, is it necessary to use the value of AAA as an input during DataLoader?

Do you mean that “TPGSR and its settings” is the TPGSR model，which published in your home page? @mjq11302010044
