Hi @ArthDh

If you want to use Cutout with PIL you could use torchtoolbox.cutout.Cutout_PIL.

Best, Devin.

[ArthDh]

It would be nice if we could have just one Cutout function that could handle both PIL and CV images!

[PistonY]

It's a good idea but need more if else and convert code, which could make code run slower. Also I have plans to Integrate with albumentations, it would be better when this finished.

[ArthDh]

We could just do a type check and call the function as needed there would be no need to convert the image in that case. Integration with albumentations sounds good!

If you have good idea please make a pr to me.
