python - tensorflow-gpu 2.2 与 CUDA 10.2 一起使用，但需要 cuDNN 7.6.4，它在 NVIDIA 存档中没有 CUDA 10.2 的下载文件

Question

错误如下，完整的日志可以在这里找到:https://pastebin.com/raw/0WQw8ktB

这些是我从 nvidia 文件中看到的:
https://developer.nvidia.com/rdp/cudnn-archive

Download cuDNN v7.6.4 (September 27, 2019), for CUDA 10.1
Download cuDNN v7.6.4 (September 27, 2019), for CUDA 10.0
Download cuDNN v7.6.4 (September 27, 2019), for CUDA 9.2
Download cuDNN v7.6.4 (September 27, 2019), for CUDA 9.0

如您所见，CUDA 10.2 没有 cuDNN，但是我需要在框架的其余部分使用 CUDA 10.2。 tensorflow-gpu 2.2 适用于 CUDA 10.2 但我收到此错误，这意味着我需要使用 cuDNN 7.6.4 而不是 7.4.2

python -c "import tensorflow as tf; print(tf.version.GIT_VERSION, tf.version.VERSION)"
v2.2.0-rc4-8-g2b96f3662b 2.2.0

已安装 cuDNN 7.6.5对于 CUDA 10.2下载后使用这些命令cudnn-10.2-linux-x64-v7.6.5.32.tgz来自英伟达官网:

$ sudo cp cuda/include/cudnn*.h /usr/local/cuda/include 

$ sudo cp -P cuda/lib64/libcudnn* /usr/local/cuda/lib64 

$ sudo chmod a+r /usr/local/cuda/include/cudnn*.h /usr/local/cuda/lib64/libcudnn*

接着:

$ export LD_LIBRARY_PATH=/usr/local/cuda-10.2/lib64:$LD_LIBRARY_PATH
