Tensorflow無法啓動

Tensorflow 1.10-GPU,好不容易安裝成功的，昨天突然報告DLL加載錯誤:

ImportError: DLL load failed with error code -1073741795

During handling of the above exception, another exception occurred:

Failed to load the native TensorFlow runtime.

網上搜索一下， 大概的意思可能是CUDA的某個庫無法加加載？

考慮到最近沒有升級過CUDA,所以排除CUDA相關的問題，或許跟最近新安裝的某個tensorflow模塊有關。

重新安裝tensorflow安裝包無效,仍然報告同樣錯誤:

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

還好之前在tesnsorflow安裝好後，把目錄 C:\Program Files\Python36 備份爲zip文件了。

現在把壞的python36目錄重命名爲python36.bad,然後解壓縮之前的zip文件爲python36目錄。

試着運行tensorflow，已經恢復正常了:
