基于ubuntu14.04 干净的系统一步步遇到的坑记录下来;

怀着平静学习的心情,问题总的能解决的!

1. 首先看了下当前python版本

python --version
Python 2.7.6

2. 安装pip

  先更新源

 sudo apt-get update

 sudo apt-get upgrade

  安装pip

  

 sudo apt-get install python-pip

  查看pip 版本

  pip -V
  pip 1.5.4 from /usr/lib/python2.7/dist-packages (python 2.7)

3.  尝试安装tensorflow,本以为安装就这么简单完成了:

tyler@pc:/opt/work/lazyzoon$ pip install tensorflow
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/tyler/.pip/pip.log

现在开始报错了

 (1). 首先怀疑的是pip版本太低,想先升级pip版本

  tyler@pc:/opt/work/lazyzoon$ pip install pip -U
Downloading/unpacking pip from https://files.pythonhosted.org/packages/d8/f3/413bab4ff08e1fc4828dfc59996d721917df8e8583ea85385d51125dceff/pip-19.0.3-py2.py3-none-any.whl#sha256=bd812612bbd8ba84159d9ddc0266b7fbce712fc9bc98c82dee5750546ec8ec64

  没办法,只能换种方法升级pip,各种google,百度,找到下面这种方法升级成功

  下载这个py脚本

wget https://bootstrap.pypa.io/get-pip.py  --no-check-certificate

  然后执行

sudo python get-pip.py

tyler@pc:/opt/work/lazyzoon$ sudo python get-pip.py

这样就安装成功了pip新版本

tyler@pc:/opt/work/lazyzoon$ pip -V
pip 19.0.3 from /usr/local/lib/python2.7/dist-packages/pip (python 2.7)

(2). 继续尝试安装tensorfolw,还是报错

sudo pip install tensorflow

markdown 3.1 has requirement setuptools>=, but you'll have setuptools 3.3 which is incompatible.

Found existing installation: six 1.5.
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.

然后发现我们本地还有python3 版本

tyler@pc:/opt/work/lazyzoon$ python3 -V
Python 3.4.

想着把python也用新版本

为了保险起见,我把之前用python2.7安装的pip卸载了

但是我发现我卸载的好像是1.5.4版本,可能这个尝试是多余。。

不管三七二十一了,用python3继续安装

这个错误是网络不稳定导致的,再次执行结果还是报错:

好像是six模块的问题,需要更新安装

成功更新了six

继续尝试安装tensorflow,果然没让我失望,还是报错

看提示可能是需要安装 python-dev

那就安装呗,sudo apt-get install python-dev

安装成功了python-dev

回来继续安装numpy

结果,还是和上次一样的报错

思考了下,我现在用的pip3,对应的python也是python3了,应该要安装 sudo apt-get install python3-dev 才对,

安装 python3-dev,

sudo apt-get install python3-dev

安装成功后,继续执行

tyler@pc:/opt/work/lazyzoon$ sudo pip3 install numpy
