Python Tensorflow under Windows 10

我正在尝试在Windows 10下在Python中获得Tensorflow GPU支持。

什么有效;

下载并安装 Python v3.7.3

pip3 install --ignore-installed --upgrade tensorflow
pip3 install --ignore-installed --upgrade scipy

从命令提示符运行 Python，然后键入导入张量流工作正常，不返回任何错误我可以在CPU上运行tensorflow Python程序(如果重要的话 https://github.com/cysmith/neural-style-tf)

什么不起作用;

我现在卸载 CPU 张量流并安装 GPU 张量流

pip3 uninstall tensorflow
pip3 install --ignore-installed --upgrade tensorflow-gpu

卸载和安装都完成，没有错误。

我下载并安装了 Cuda 工具包 9.0 和补丁。

我下载并提取 cuDNN 并将相关 DLL 复制到 C：\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v9.0 下的文件夹中

C：\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v9.0\extras\demo_suite\oceanFFT.exe 按预期运行，所以我现在假设 Cuda 安装正确

从命令提示符窗口运行 Python

类型导入张量流

失败并出现这些错误...

路径在开头有 Cuda 条目，即

PATH=C:Program FilesNVIDIA GPU Computing ToolkitCUDAv9.0bin;C:Program FilesNVIDIA GPU Computing ToolkitCUDAv9.0libnvvp;

我尝试卸载 Cuda v9 并尝试了 v8 和最新的 v10。同样的错误。

任何想法我需要做什么才能让 tensorflow GPU 在 Windows 10 中的 Python 下工作？

在看到一些帖子说不支持 v3.7 后，还尝试了较旧的 Python v3.6.8。

相同的错误

我也回到了Python v3.5.2，安装了tensorflow-gpu并得到了同样的错误......

因此，在我疯狂地尝试 Python、Cuda 和 cuDNN 的每个组合希望获得工作匹配之前，是否有任何实际步骤可以安装哪个版本以及完成此操作的顺序？

编辑：我需要/用于制作这项工作的版本是;

已安装的 Python v3.6.4

pip3 install --no-cache-dir --ignore-install --upgrade tensorflow-gpu==1.12.0

pip3 安装 --no-cache-dir --忽略-安装 --升级 scipy

pip3 安装 --no-cache-dir --忽略已安装 --升级 opencv_python-3.4.5-cp36-cp36m-win_amd64.whl

库达 9.0

cuDNN 需要"下载 cuDNN v7.2.1(2018 年 8 月 7 日)，适用于 CUDA 9.2">

来自 Tensorflow 安装

视窗设置

请参阅上面列出的硬件要求和软件要求。阅读适用于 Windows 的 CUDA® 安装指南。

确保安装的 NVIDIA 软件包与版本匹配上面列出。特别是，TensorFlow 不会在没有 cuDNN64_7.dll文件。若要使用其他版本，请参阅 Windows 内部版本来自源指南。

也许您没有指定的文件cuDNN64_7.dll

请检查该文件是否存在于 C：\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v9.0\bin 中其中 9.0 是 CUDA 的版本

实际上，我在Windows 10中可以使用此设置

蟒蛇 3.6.4
张量流 1.12.0
库达 9.0

编辑：一些研究我发现这与该问题有关
