python - 尝试在 GPU 上运行时如何修复 "Failed to load the native TensorFlow runtime."错误？

Question

我一直在我的 CPU 上运行我的 tensorflow 程序。然而，它变得越来越慢，所以我想设置一个 GPU 环境来在我的 1070ti 上运行它。但是，当下载 CUDA 9.0 和 CUDNN 7.4 后，tensorflow-gpu 运行时遇到问题。

每当我尝试在 python 中导入tensorflow时，就会出现错误。我在 virtualenv 环境中安装了tensorflow，并且运行的脚本位于该文件夹内。

import tensorflow

我得到以下输出:

Traceback (most recent call last):
  File "C:\Users\Jimmy\Documents\machinelearning\machinelearning\lib\site-packages\tensorflow\python\pywrap_tensorflow.py", line 58, in <module>
    from tensorflow.python.pywrap_tensorflow_internal import *

    _mod = imp.load_module('_pywrap_tensorflow_internal', fp, pathname, description)

    return load_dynamic(name, filename, file)
  File "C:\Users\Jimmy\Documents\machinelearning\machinelearning\lib\imp.py", line 343, in load_dynamic
    return _load(spec)
ImportError: DLL load failed: The specified module could not be found.

During handling of the above exception, another exception occurred:

根据this thread ，这些软件包不适用于 Windows 10:

• tensorflow 1.12.0
• Cuda 工具包 10.0.130
• cudnn 7.4.1.5

但是，有人说你可以尝试使用pip将Tensorflow降级到1.10版本:

pip install tensorflow-gpu==1.10.0
