The use of set_format("torch") on Hugging Face datasets can sometimes result in a TypeError: 'NoneType' object is not callable because set_format mutates the dataset in place and may return None. A safer alternative is to use with_format("torch"), which creates a formatted view of the dataset without mutating the original, preventing this error.
