undefined reference to `cudnnCreate@libcudnn.so.7'

I download TensorRT-3.0.2.Ubuntu-16.04.3.x86_64.cuda-9.0.cudnn7.0.tar from nvidia homepage. And I used it in the environment of cuda-9.0 and cudnn-7.0. But I encounter the problem of such libnvinfer.so: undefined reference to `cudnnCreate@libcudnn.so.7’. Does anybody encounter this problem?

I had solved this problem by updating cudnn Library.
