Thanks for the PR! Just a style check not passing, you need to split the line 34 which is too long in 2 :)

@charlesmindee Thanks for your comment, I have added the new commit of style fix.
However, can you give me a help on how to use the library on Vietnamese OCR please ? Do I have to change something or just applying the new vocabs ?

Hi @calibretaliation, if you want to use the librairy on Vietnamese OCR, you need to apply the you new vocab on a recognition model, you can keep the detection model as it is. However, you need to retrain the recognition model on you vocabulary with a labelled vietnamese dataset of word crops. For your PR, it would indeed be nice to indent so that flake8 is running without raising any error 🙏

[charlesmindee]

You need to align everything under the parenthesis, otherwise it is OK!

Thanks!

Missing PR labels here as well @charlesmindee :)

Also, perhaps we should add specific contribution guidelines for vocab addition? I remember that for portuguese we had back & forth iterations, so perhaps we could ask to add a reference in the PR or better, as a comment in the code?

There are also missing additions in the documentation for the last added vocabs
