ubuntu 安装 tensorflow 提示pip版本不对

Question

1 本人在ubuntu16.04LTS， python版本2.7&3.5.2，上用pip安装tensorflow，结果提示pip太旧了，我更新了pip也没用，以下是报错信息

You are using pip version 8.1.1, however version 10.0.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

我查看了一下pip的版本：
yc_qian@QYC:~$ pip -V
pip 10.0.1 from /home/yc_qian/.local/lib/python3.5/site-packages/pip (python 3.5)

保险起见，又看了pip3的版本：
yc_qian@QYC:~$ pip3 -V
pip 10.0.1 from /home/yc_qian/.local/lib/python3.5/site-packages/pip (python 3.5)

明明pip版本都是10.0.1了，为什么安装tensorflow还会失败？请问我该怎么办？

Answer 1

pip

你可以试一下sudo pip -V,肯定是8.0.1
linux我也不是很熟,但是我知道加不加sudo安装的东西,位置不一定是一样的,你sudo安装的东西,不用su可能会无法使用.

TF

你安装的时候下面的一大串提示的意思是,

你要安装的所有依赖包都已经安装完成了,对了提醒你一句,你的pip还是8.0.1,最新版本已经是10.0.1了,你可以更新一下.

就是说TF已经安装完了.不过在SU环境下.

Answer 2

刚刚评论区有朋友指出可能是venv的问题，我试了试sudo pip3 -V 和sudo pip -V，果然，pip版本号是8……因为我是用sudo来安装tensorflow的……于是，只要sudo更新一下pip即可

Answer 3

建议使用anaconda直接安装TF

Answer 4

这个问题嘛，其实和tensorflow没什么关系：
看下里面的提醒：

You are using pip version 8.1.1, however version 10.0.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

意思是：你当前使用的pip版本是8.1.1，但是最新版本是10.0.1。
你可以(should)考虑升级，但是你也可以不升级啊，不影响的！！
