GPU上的Tensorflow

我已经能够在CPU上使用TensorFlow，现在我需要在具有以下规格的GPU设备上运行它:

I've been able to work with TensorFlow on CPU, Now I need to run it on a GPU device with the following specs:

CPU:Intel Xeon(E5-2670)和win7 64bit和NVIDIA GeForce GTX 980 Ti

我已经按照TF主页中的说明安装了适用于GPU的python3.5和Tensorflow.当我在此处运行测试程序时，尝试import Tensorflow会得到什么:

I've installed python3.5 and Tensorflow for GPU just as described in TF homepage. when I run a test program here what I get when I try to import Tensorflow :
