在Windows上导入Tensorflow时出错

Question

我在尝试导入tensorflow时遇到这个错误：

Traceback (most recent call last):
  File "C:\Users\Luca\AppData\Local\Programs\Python\Python36\lib\site-packages\tensorflow\python\platform\self_check.py", line 75, in preload_check
    ctypes.WinDLL(build_info.cudart_dll_name)
  File "C:\Users\Luca\AppData\Local\Programs\Python\Python36\lib\ctypes\ \__init__.py", line 348, in \__init__
    self._handle = _dlopen(self._name, mode)
OSError: [WinError 126] Impossibile trovare il modulo specificato

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "<pyshell#1>", line 1, in <module>
    import tensorflow as tf
  File "C:\Users\Luca\AppData\Local\Programs\Python\Python36\lib\site-packages\tensorflow\__init__.py", line 24, in <module>

ImportError: Could not find 'cudart64_80.dll'. TensorFlow requires that this DLL be installed in a directory that is named in your %PATH% environment variable. Download and install CUDA 8.0 from this URL: https://developer.nvidia.com/cuda-toolkit

我已经尝试过卸载protobuf和tensorflow并再次安装它，但是仍然出现此错误。

这些是我的规格：

作业系统：W10

GPU：英伟达GTX 1050 Ti

有人能帮我吗？

您是否尝试过从https://developer.nvidia.com/cuda-toolkit下载Cuda 8.0
