Python3.6安装tensorflow-GPU

Win10下Python3.6安装tensorflow-gpu总结

1 安装工具（Anaconda）

网络上各种安装Python库的方式。经过本人实践，最方便的方式还是用Anaconda安装。安装指令也很简单。

       在CMD界面中输入：conda install * (* 为对应库名)，例如conda install numpy.

2 CUDA 和cudnn选择

Python3.6版本需用CUDA8.0和cudnn6.切记

不然导入错误：

importtensorflow as tf
Traceback (most recent call last):
  File "D:\ProgramFiles\Python35\lib\site-packages\tensorflow\python\pywrap_tensorflow_internal.py",line 18, in swig_import_helper
    return importlib.import_module(mname)

3 安装TensorFlow-GPU

Python3.6 对应的Tensorflow-gpu需要1.3.0以上版本。

可用三种方式安装：

A： pip installtensorflow-gpu

B :  pip install *.whl

C : 已经安装过tensorflow的建议用如下指令升级

       pip3 install –ignore-installed –upgrade tensorflow-gpu

       将会安装最新版本tensorflow.

笔者走过弯路，先用的清华的镜像，安装的低版本，然后用的C方式进行了升级。

安装完成后，依次在控制台输入：

 cmd->python->import tensorflow as tf

无报错，则成功。
