I want to know about compatibility of CUDA, cudnn and tensorflow

I installed tensorflow 2.0.0 with keras 2.3.0 and downloaded CUDA 10.0
then, to use GPU, should I download CUDNN 7.4.1 ?
In NVIDIA, it says only 7.4 like image uploaded

thus, my question is,
which version of cudnn work in the environment in tensorflow 2.0.0, keras 2.3.0 and CUDA 10.0 ?
