- I uninstalled all NVIDIA drivers and CUDA.

- Restarted PC

- Installed CUDA 10.2 (cuda_10.2.89_441.22_win10)

- Then Copied cudnn(cudnn-10.2-windows10-x64-v8.0.2.39) as mentioned [here](https://docs.nvidia.com/deeplearning/sdk/cudnn-install/index.html#installwindows)
Copy <installpath>\cuda\bin\cudnn*.dll to C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v10.2\bin.
Copy <installpath>\cuda\include\cudnn*.h to C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v10.2\include.
Copy <installpath>\cuda\lib\x64\cudnn*.lib to C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v10.2\lib\x64.

- Ensured the following values are set:
Variable Name: CUDA_PATH 
Variable Value: C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v10.2
