I think this has something to do with processor. While saving the model weights you are supposed to save the config related files as well. so don’t forget to do this:
processor = TrOCRProcessor.from_pretrained("microsoft/trocr-base-printed")
model = VisionEncoderDecoderModel.from_pretrained("microsoft/trocr-base-printed")
# do some config changes...
# train or whatever
processor.save_pretrained('test')
model.save_pretrained('test')
and then load it from test. I guess you won’t see this line then.
