GPU 上的张量流

Question

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

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

我已经安装了 python3.5 和 Tensorflow for GPU，就像 TF 主页中描述的那样。当我运行一个测试程序时，我尝试 import Tensorflow 时得到的结果：

    (C:\Users\Engine>python
Python 3.5.3 (v3.5.3:1880cb95a742, Jan 16 2017, 16:02:32) [MSC v.1900 64 bit (AM
D64)] on win32
Type "help", "copyright", "credits" or "license" for more information.

有没有人知道如何解决这个问题？

Answer 1

CUDNN 可能是原因之一。 cuDNN v6.0 不适用于很多人。尝试使用 cuDNN v5.1。
从GIT文件夹中导入也是原因之一。

很高兴知道 1 对你有用。
