Solutions to update Cudnn

[BairenChen]

Problem descriptions:
Loaded runtime CuDNN library: 7.1.4 but source was compiled with: 7.6.5. CuDNN library major and minor version needs to match or have higher minor version in case of CuDNN 7.0 or later version. If using a binary install, upgrade your CuDNN library. If building from sources, make sure the library loaded at runtime is compatible with the version specified during compile configuration.
