Error when importing Tensorflow on Windows

Question

I get this erro trying to importing tensorflow:

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>

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

I've alredy tried to uninstall protobuf and tensorflow and install it again, but still get this error.

Those are my specs:

OS : W10

GPU : Nvidia GTX 1050 Ti

Can someone help me?
