training own datasets with funsd type using layoutlmv3

[Chaoran-F]

Describe
Model I am using (LayoutLMv3):

I plan to use the layoutlmv3 model to fine-tune my own dataset. The format of my dataset is created in the ”funsd“ style, but I haven't found any guidance on how to fine-tune my own dataset. Could anyone possibly give me a rough path? I tried the method in the readme, but it didn't work.
