如何修复“无法加载本机 TensorFlow 运行时”。 尝试在 gpu 上运行时出错？

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环境在我的1070ti上运行它。 但是，在下载 CUDA 9.0 和 CUDNN 7.4 后，tensorflow-gpu 无法运行。

每当我尝试在 python 中导入 tensorflow 时都会出现错误。 我在 virtualenv 环境中安装了 tensorflow，并且运行的脚本在文件夹内。

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 *
  File "C:\Users\Jimmy\Documents\machinelearning\machinelearning\lib\site-packages\tensorflow\python\pywrap_tensorflow_internal.py", line 28, in <module>
    _pywrap_tensorflow_internal = swig_import_helper()
  File "C:\Users\Jimmy\Documents\machinelearning\machinelearning\lib\site-packages\tensorflow\python\pywrap_tensorflow_internal.py", line 24, in swig_import_helper
    _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:

根据这个线程，这些包在 Windows 10 上不起作用：

• TensorFlow 1.12.0
• Cuda 工具包 10.0.130
• cudnn 7.4.1.5

但是，有人说可以尝试使用 pip 将 Tensorflow 降级到 1.10 版本：

pip install tensorflow-gpu==1.10.0
