Tensorflow现已在Windows上提供:
https://developers.googleblog.com/2016/11/tensorflow-0-12-adds-support-for-windows.html
我使用了pip install tensorflow。
我尝试运行介绍代码:
https://www.tensorflow.org/versions/r0.12/get_started/index.html
我收到此错误:
C:\Python\Python35-32\python.exe "C:/tensorflow_tutorial.py"

ImportError: DLL load failed: %1 is not a valid Win32 application.
这个网站有一些关于DLL的建议,但是任何人都猜错了:

更新:我切换到x64我收到此错误:
I c:\tf_jenkins\home\workspace\release-win\device\gpu\os\windows\tensorflow\stream_executor\dso_loader.cc:119] Couldn't open CUDA library cublas64_80.dll

UPDATE2:
我安装了nvidia cuda文件
https://developer.nvidia.com/cuda-downloads
我收到这些错误:
I c:\tf_jenkins\home\workspace\release-win\device\gpu\os\windows\tensorflow\stream_executor\dso_loader.cc:128] successfully opened CUDA library cublas64_80.dll locally

UPDATE3:
我从NVIDIA注册并下载了cudnn packge
https://developer.nvidia.com/cudnn
移动了文件位置
C:\Desktop\cudnn-8.0-windows10-x64-v5.1.zip\cuda\bin\cudnn64_5.dll to C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v8.0\bin\cudnn64_5.dll
仍然出现此错误:
I c:\tf_jenkins\home\workspace\release-win\device\gpu\os\windows\tensorflow\stream_executor\dso_loader.cc:119] Couldn't open CUDA library nvcuda.dll
更新4:
将nvcuda.dll下载到C:\ Program Files \ NVIDIA GPU Computing Toolkit \ CUDA \ v8.0 \ bin
这解决了我的问题。
答案 0 :(得分:3)
从Python解释器的路径(C:\Python\Python35-32
)看来,您使用的是32位版本的Python 3.5。官方TensorFlow软件包仅适用于64位体系结构(x64
/ amd64
),因此您有两种选择:
安装Python 3.5的64-bit version(来自Python.org或Anaconda),或
自行编译PIP包以获取32位Python 3.5。您可以使用实验性CMake构建来执行此操作(有关详细信息,请参阅here),但这不是受支持或测试的配置。
(请注意,我不确定您是如何在32位版本的Python上安装软件包的,因为当我尝试这样做时,我收到一条错误消息:“此平台上不支持此轮。”)< / p>

问题不在于平台(amd64),而在于GPU驱动程序。您需要安装在CPU上运行的软件包或使用已安装的GPU,但也要安装CUDA驱动程序。
答案 2 :(得分:0)
你可以在&#34; cuda \ bin&#34; [这是cudnn-8.0-windows7-x64-v5.1_4 zip提取文件夹]中找到cudnn64_5.dll文件。然后复制上面将文件存入&#34; C:\ Program Files \ NVIDIA GPU Computing Toolkit \ CUDA \ v8.0 \ bin&#34; 。 这适用于Python 3.5 bit 64版本和Windows 7 bit 64环境

如果您要安装GPU版本,请确保您的系统具有以下功能:
