OCR Model. What's "anchor-words", and how to define them?

I build a OCR Model to get the code(商品コード)] from photo. But got the warning below.

“A warning was produced while training OCR Model ‘Read Code 2’: No anchor-words were found; defaulting to using top-left corner and document size for alignment.”

My question is how to make my anchor words(I think it’s “商品コード”) to be found.

Same as me.

Having the same problem. Anyone found out what this “anchor words” are?

Any luck yet people? I have also been facing that issue all week

OCR is designed to be used with well-structured images, such as pictures of forms. It is not designed to work with arbitrary images.

An “anchor word” would be a word or words that appear in every image (such as the questions on a survey form) that would help the OCR recognize what form it’s seeing and where in the form it’s at.
