缺少DLL和pywrap_tensorflow。 Tensorflow-gpu安装错误

Question

我想在anaconda环境（python版本3.5）中安装tensorflow-gpu。但是，我得到了一些错误，主要是：

• DLL加载失败
• 没有名为“_pywrap_tensorflow_internal”模块

看来，这个错误是很常见的，但是，我不知道为什么来自另一个问题的解决方案不起作用。

1. 我在我的路径中有一个MSVCP140.DLL。我通过where MSVCP140.DLL进行检查。这是修复建议here。
2. 我已经从here和来自here的cuDNN 5.1（而不是cuDNN 6.0）安装了CUDA 8.0。
3. 我已经添加了cudnn64_5.dll（... \ bin）的路径
4. tensorflow的CPU版本运行正常，没有错误。

我试过重装CUDA和tensorflow-gpu，但它仍然不起作用。任何帮助？

Answer 1

我有完全相同的问题很长一段时间，似乎刚才解决了这个问题对我来说。

安装cuDNN 6.0并确认cuda/bin中的dll名称为cudnn64_6.dll。只将名称更改为cudnn64_5.dll（并确保它已添加到您的路径中）。

希望这会解决您的问题。
