Hi
I am attempting to install CUDA in order to run tensorflow on my computer, however I am experiencing some difficulty. I have looked in several forum posts, and can not find a solution
Install went fine, but when i try to run the tests specified in the install guide, i run into some obstacles.
running deviceQuery.exe works fine:
C:\ProgramData\NVIDIA Corporation\CUDA Samples\v9.0\bin\win64\Debug>deviceQuery.exe

BUT: When running bandwithTest.exe i get the following error message:

I get the passed score for device to device, and device to host, but host to device fails…:

Any help would be greatly appreciated!
