Windows 上的 TensorFlow : ImportError: No module named '_pywrap_tensorflow_internal'

Question

我正在尝试让 TensorFlow 在 Windows 上运行。但是在安装 Python 3.5 和 TensorFlow 后，我在导入 TensorFlow 模块时不断收到以下错误:

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

During handling of the above exception, another exception occurred:

Failed to load the native TensorFlow runtime.

See https://www.tensorflow.org/install/install_sources#common_installation_problems

请提出我所缺少的内容，以便可以删除上述运行时错误。

当找不到 TensorFlow 所依赖的库 (DLL) 之一时，会出现此错误。为了诊断这种错误，我编写了一个脚本，您可以下载 from here ;运行该脚本将打印有关采取哪些步骤来修复错误的建议。

如果您正在运行仅 CPU 版本的 TensorFlow，最有可能丢失的 DLL 是 MSVCP140.DLL .它是 Microsoft Visual C++ Redistributable Update 3 的一部分，您可以从 here 下载。 .

如果您运行的是 GPU 版本的 TensorFlow，则可能找不到 CUDA 库或 cuDNN 库。 Windows 上的 TensorFlow 支持 CUDA 8.0(从 here 下载)和 cuDNN 5.1(从 here 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您的 %PATH% 中。环境变量。
