python3安装tensorflow遇到的问题

1. 使用命令：sudo pip3 install --upgrade \ https://storage.googleapis.com/tensorflow/linux/cpu/tensorflow-1.1.0rc2-cp35-cp35m-linux_x86_64.whl 安装。

遇到如下问题：

tensorflow-1.1.0rc2-cp35-cp35m-linux_x86_64.whl is not a supported wheel on this platform.

试过好几个版本都报相同的错误，不支持平台。

2. 换命令 pip3 install  tensorflow 安装。

遇到如下问题：

Downloading/unpacking tensorflow
      Could not find any downloads that satisfy the requirement tensorflow
Cleaning up...
      No distributions at all found for tensorflow
      Storing debug log for failure in /home/itcast/.pip/pip.log

(1) 有说tensorflow不支持32位系统只支持64位系统的，特意用命令sudo uname --m查看系统是x86_64，说明是64位。

     另 查到这个问题原因是： pip3的版本太低。

  使用命令 pip3 -V  可查看版本：pip 1.5.4 from /usr/lib/python3/dist-packages (python 3.4) 

  参考：https://blog.csdn.net/sisiel/article/details/77540236， https://blog.csdn.net/zhangchuang601/article/details/79387725。 

(2) 然后使用网上公认的升级命令： pip3 install --upgrade pip。 

此次升级可行，如果不行可参考   https://blog.csdn.net/zhangchuang601/article/details/79387725 ：

$ sudo easy_install --upgrade pip  #运行后解决问题。
$ sudo easy_install --upgrade six   #这个不用也行

(3) 然后再执行 pip3 install  tensorflow 可以顺利往下走了，然后遇到如下问题：

Cannot uninstall 'six'. It is a distutils installed project and thus we cannot accurately determine which files belong to it which would lead to only a partial uninstall.

3. 使用 sudo pip3 install --ignore-installed six 命令安装好six 

此命令借鉴于：https://blog.csdn.net/xiaoxianerqq/article/details/80579113 。

然后继续 pip3 install  tensorflow 终于安装完成了。

4. 测试

$ python3
Python 3.4.3 (default, Nov 28 2017, 16:41:13)
[GCC 4.8.4] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import tensorflow
>>> tensorflow.constant(3)
<tf.Tensor 'Const:0' shape=() dtype=int32>
>>>

 应该可以正常使用了。
