Windows 10下的Python Tensorflow

Question

我正在尝试在Windows 10下的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import tensorflow Works，并且不返回任何错误，我可以在CPU上运行tensorflow Python程序（如果重要的话， 请访问https://github.com/cysmith/neural-style-tf ）

什么不起作用；

我现在卸载CPU tensorflow并安装GPU tensorflow

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

卸载和安装均无错误。

我下载并安装了Cuda Toolkit 9.0和补丁。

我下载并提取cuDNN并将相关的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已正确安装

从命令提示符窗口运行Python

输入import tensorflow

由于这些错误而失败...

路径正确地在开头有Cuda条目，即

PATH=C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v9.0\bin;C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v9.0\libnvvp;

我尝试卸载Cuda v9，并尝试了v8和最新的v10。 同样的错误。

我有什么想法要让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。

同样的错误

因此，在我尝试使用Python，Cuda和cuDNN的每一个组合而发疯之前，都希望能找到可行的解决方案，请问有什么实际步骤安装哪个版本以及安装该版本的顺序？

编辑：我需要/用来完成这项工作的版本是；

已安装Python v3.6.4

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

pip3 install --no-cache-dir --ignore-installed --upgrade scipy

pip3 install --no-cache-dir --ignore-installed --upgrade opencv_python-3.4.5-cp36-cp36m-win_amd64.whl

酷达9.0

cuDNN需要为“为CUDA 9.2下载cuDNN v7.2.1（2018年8月7日）”

Answer 1

从Tensorflow安装

Windows设置

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

确保已安装的NVIDIA软件包与上面列出的版本匹配。 特别是，如果没有cuDNN64_7.dll文件，TensorFlow将不会加载。 要使用其他版本，请参阅Windows源代码指南。

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其中9.0是CUDA的版本

其实我在Windows 10中有此设置

• 的Python 3.6.4
• Tensorflow 1.12.0
• CUDA 9.0

Answer 2

对于所有在Windows 10 / Python 3.6.x / RTX20xx下具有“ DLL加载失败”问题的用户。

CUDA 10.0（不是10.1！）和cuDNN 7.5.0的组合对我来说很好（截至2019年4月12日）。 我还安装了Visual Studio 2015（但不确定是否需要）。

不要忘记将cuDNN * .dll文件的位置（在CUDA目录中的/bin/目录）添加到PATH中。

如果您具有CUDA 10.1，只需将其卸载，安装10.0，将cuDNN文件添加到10.0目录中，然后重新启动。

可以使用pip install tensorflow-gpu
