本文详细记录了解决TensorFlow GPU版本1.10在Windows环境下出现DLL加载失败错误（错误代码-1073741795）的过程。通过排除CUDA问题并尝试重新安装TensorFlow未果后，最终通过恢复之前备份的Python环境解决了该问题。

Tensorflow 1.10-GPU,好不容易安装成功的，昨天突然报告DLL加载错误:

ImportError: DLL load failed with error code -1073741795

During handling of the above exception, another exception occurred:

Failed to load the native TensorFlow runtime.

网上搜索一下，大概的意思可能是CUDA的某个库无法加加载？

考虑到最近没有升级过CUDA,所以排除CUDA相关的问题，或许跟最近新安装的某个tensorflow模块有关。

重新安装tensorflow安装包无效,仍然报告同样错误:

pip install tensorflow_gpu-1.10.0-cp36-cp36m-win_amd64.whl

还好之前在tesnsorflow安装好后，把目录 C:\Program Files\Python36 备份为zip文件了。

现在把坏的python36目录重命名为python36.bad,然后解压缩之前的zip文件为python36目录。

试着运行tensorflow，已经恢复正常了:
