        Returns:
            A `ShieldGemma2ImageClassifierOutputWithNoAttention` instance containing the logits and probabilities
            associated with the model predicting the `Yes` or `No` token as the response to that prompt, captured in the
            following properties.

                *   `logits` (`torch.Tensor` of shape `(batch_size, 2)`):
                    The first position along dim=1 is the logits for the `Yes` token and the second position along dim=1 is
                    the logits for the `No` token.
                *   `probabilities` (`torch.Tensor` of shape `(batch_size, 2)`):
                    The first position along dim=1 is the probability of predicting the `Yes` token and the second position
                    along dim=1 is the probability of predicting the `No` token.

            ShieldGemma prompts are constructed such that predicting the `Yes` token means the content *does violate* the
            policy as described. If you are only interested in the violative condition, use
            `violated = outputs.probabilities[:, 1]` to extract that slice from the output tensors.

            When used with the `ShieldGemma2Processor`, the `batch_size` will be equal to `len(images) * len(policies)`,
            and the order within the batch will be img1_policy1, ... img1_policyN, ... imgM_policyN.
