tensorflow 安装正确但出现错误“ImportError: No module named '_pywrap_tensorflow_internal' on import tensorflow as tf

Question

我按照此处https://www.tensorflow.org/install/install_windows的说明使用两种安装选项（使用anaconda虚拟环境以及直接使用python安装）正确安装了tensorflow。

每次我看到这个错误：

我正在 Windows 7 上安装最新的 tensorflow cpu 版本，cuda 9.0 和 cuDNN64_7.dll、MSVCP140.dll 在我的 PATH 变量中都正确。在我放弃之前，我尝试了 python 3.6.4 (64bit)、3.5.2(64bit) 和 3.5.3(64bit)。

*注意- 还查看了该页面上列出的所有常见安装问题。但没有运气。*

Answer 1

经过数小时的挖掘，以下事情奏效了：

1. 安装 CUDA 8.0 和
2. cuDNN 5.1，

3. 将我的 tensorflow 安装从 1.6 降级到 1.5.1 [用户关注答案install tensorflow with specific version on Anaconda

4. 添加以下路径变量

C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v8.0\extras\CUPTI\libx64 C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v8.0\lib\x64
