The predicion do not display anything at all when I was training

[monarchmio]

Previously, when I trained on Japanese data, the predictions only displayed or the same character. Then, I downgraded the transformers version to 4.25.1, which resulted in a "NotImplementedError: Make sure _init_weights is implemented for <class 'donut.model.DonutModel'>" error. I resolved this error by modifying the class pretrained model method in the relevant Python file according to the new version. However, now when I train, the predictions do not display anything at all. I'm not sure where the issue lies; do I need to change any settings for my Japanese dataset?
