@sushmanthreddy For BetterTransformer tests, they are all here: https://github.com/huggingface/optimum/tree/main/tests/bettertransformer
You can run them with pytest tests/bettertransformer for instance. But some of them will probably fail if you don't have a GPU.

Yes I second what @regisss said !
To run the styling checks just run

make style

(and not make quality :D )
For the tests you can start over by just running pytest tests/bettertransformer

@regisss @younesbelkada I think my code wasn't passing some of the checks ...can u pls just give some hint where I was going wrong??

I think many tests failed because you wrote DETR in upper case in the test files, while it shoud be in lower case: detr.
