无法在 Python 中导入 tensorflow-gpu

Question

我已经使用 conda 安装了 tensorflow-gpu，在此之前我已经安装了 CUDA Toolkit 9.0 和 CuDNN v7.0。但是在尝试运行 hello tensorflow 代码后，我遇到了以下错误。无法加载 lib 文件。

以下是我作为 I/p 给出的内容：

Microsoft Windows [Version 10.0.15063]
(c) 2017 Microsoft Corporation. All rights reserved.

C:\Users\Manish>activate tensorflow-gpu

(tensorflow-gpu) C:\Users\Manish>python
Python 3.6.1 |Continuum Analytics, Inc.| (default, May 11 2017, 13:25:24) [MSC v.1900 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import tensorflow as tf

这是之后的错误

按照以下步骤使用 conda 安装 Tensorflow

#Set Up Anaconda Environments
conda create --name tf_gpu python=3

#Activate the new Environment
source activate tf_gpu

# Install CUDA and cuDNN
tf_gpu$conda install -c anaconda cudatoolkit=9.0 cudnn=7.0

#Install Tensorflow
tf_gpu$ conda install -c anaconda tensorflow-gpu
