Higher value makes the processing do fewer lookups, lower value consume less temporary memory while running `map`.
            train_new_fingerprint (`str`, *optional*, defaults to `None`):
                The new fingerprint of the train set after transform.
                If `None`, the new fingerprint is computed using a hash of the previous fingerprint, and the transform arguments
            test_new_fingerprint (`str`, *optional*, defaults to `None`):
                The new fingerprint of the test set after transform.
                If `None`, the new fingerprint is computed using a hash of the previous fingerprint, and the transform arguments
