Other way. You can copy/paste step lr scheduler code from pytorch to your project and add redefined print_lr function
Something like this should work:
def print_lr(self, is_verbose, group, lr, epoch=None):
    """Display the current learning rate.
    """
    if is_verbose and ((self._step_count - 1) % self.step_size == 0):
        if epoch is None:
            print(self._step_count)
            print('Adjusting learning rate'
                    ' of group {} to {:.4e}.'.format(group, lr))
        else:
            print('Epoch {:5d}: adjusting learning rate'
                    ' of group {} to {:.4e}.'.format(epoch, group, lr))
