About sru_cuda_kernel.cu

[LittleRooki]

Hi, I want to verify that my implementation of sru is correct, so I want to know more details.
Can you tell me how to printf in sru_cuda_kernel.cu, for example：

        const auto u0 = *up;
        const auto u1 = *(up + 1);
        const auto u2 = *(up + 2);
        const auto wc1 = *vp1;
        const auto wc2 = *vp2;
        const auto x_val = (skip_type) ? (*xp) : (scalar_t)0.f;
        const auto g1 = sigmoidf(u1 + wc1*cur + bias1);
        const auto g2 = sigmoidf(u2 + wc2*cur + bias2);
        cur = (cur-u0)*g1 + u0;
        const auto val = calc_activation(activation_type, cur);
        *hp = skip_type ? ((val - x_val) * mask * g2 + x_val) : (val * mask * g2);

I want to know how to printf wc1, wc2 and g1? Can you give me some help?

hi @hangcao1004
Wouldn't directly adding printf work? See
