"Download cuDNN in [NVIDIA cuDNN | NVIDIA Developer](https://developer.nvidia.com/cudnn), according to [PaddlePaddle Installation Steps](https://www.paddlepaddle.org.cn/install/quick) requirements, we **need to use cuDNN 7.6.5+**, so we can download the version 7.6.5 of cuDNN that supports CUDA 10.2. After downloading cuDNN, unzip it. Assuming the installation path of our CUDA is `C:\\Program Files\\NVIDIA GPU Computing Toolkit\\CUDA\\v10.2`. After decompressing cuDNN, we take the files in `bin`, `include` and `lib` and replace the corresponding original files in the CUDA installation path (if the file already exists, replace it, if it does not exist, paste it directly into the corresponding directory). At this point, cuDNN has been installed.\n",
