Before Change

        // batch_dims and diag
        res = kernel(a, b, batch_dims=(0, 2)).diag()
        actual = torch.cat([actual[i].diag().unsqueeze(0) for i in range(actual.size(0))])
        self.assertLess(torch.norm(res - actual), 1e-5)

After Change

        // batch_dims
        double_batch_a = scaled_a.unsqueeze(0).transpose(0, -1)
        double_batch_b = scaled_b.unsqueeze().transpose(0, -1)
        actual = double_batch_a.transpose(-1, -2).unsqueeze(-1) - double_batch_b.transpose(-1, -2).unsqueeze(-2)
        actual = actual.pow(2).mul_(-0.5).exp().view(3, 2, 2, 2)
        actual[:, 1, :, :].mul_(2)
