Windows上的TensorFlow:ImportError:没有名为'_pywrap_tensorflow_internal'的模块

Question

我试图让TensorFlow在Windows上运行.但是在安装Python 3.5和TensorFlow之后,我在导入TensorFlow模块时出现以下错误:

>>>import tensorflow
Traceback (most recent call last):
  File "C:\Users\amit\AppData\Local\Programs\Python\Python35\lib\site-packages\

Failed to load the native TensorFlow runtime.

请建议我的结果中缺少什么,以便可以删除上面的运行时错误.

当无法找到TensorFlow所依赖的库(DLL)之一时,会出现此错误.为了诊断这种错误,我编写了一个可以从这里下载的脚本; 运行该脚本将打印有关修复错误的步骤的建议.

• 如果您运行的是仅CPU版本的TensorFlow,则最不可能的DLL是MSVCP140.DLL.它是Microsoft Visual C++ Redistributable Update 3的一部分,您可以从此处下载.

• 如果您运行的是TensorFlow的GPU版本,则可能无法找到CUDA库或cuDNN库.Windows上的TensorFlow支持CUDA 8.0(从这里下载)和cuDNN 5.1(从这里下载).请注意,cuDNN通常安装在与CUDA不同的目录中,您可能需要手动将其添加到%PATH%环境变量中.
