  outputs (`torch.FloatTensor` of shape `(batch_size, channels, seq_len)`:
            Hidden-states as transformed by the piecewise rational quadratic function with the `tail_bound` limits
            applied.
        log_abs_det (`torch.FloatTensor` of shape `(batch_size, channels, seq_len)`:
            Logarithm of the absolute value of the determinants corresponding to the `outputs` with the `tail_bound`
            limits applied.
