In huggingface dataset, i found two ways of transformation. [with\_transform](https://huggingface.co/docs/datasets/package_reference/main_classes#datasets.Dataset.with_transform) and [set\_transform](https://huggingface.co/docs/datasets/v2.3.2/en/package_reference/main_classes#datasets.Dataset.set_transform)  
What is the difference between two and which one to use in image classification

Hi! The only difference is that `set_transform` modifies a dataset in-place and `with_transform` returns a new dataset with the specified transform. Which of these two approaches you want to use is up to you.
