[英]Upgrade to numpy 1.8.0 on Ubuntu 12.04
I'm running Ubuntu 12.04 which comes by default with NumPy 1.6.0
(I have, actually had , Python 2.7.3
installed). 我运行Ubuntu 12.04自带其默认使用NumPy 1.6.0
(我,其实是有 , Python 2.7.3
安装)。 As a result of the answer to this question polyfit() got an unexpected keyword argument 'w' , I need to upgrade it. 由于回答这个问题, polyfit()得到了一个意想不到的关键字参数'w' ,我需要升级它。
I downloaded the .tar.gz
package for the version 1.8.0
from here , unpacked it, moved inside the folder and run the commands: 我从这里下载了版本1.8.0
的.tar.gz
包,解压缩,移动到文件夹中并运行命令:
python setup.py build --fcompiler=gnu95
python setup.py install --user
as described in the user guide and in this question: Building NumPy 1.7.1 on Ubuntu . 如用户指南和此问题中所述: 在Ubuntu上构建NumPy 1.7.1 。
This resulted in NumPy
no longer loading in Spyder
, which now shows the error: 这导致NumPy
不再加载Spyder
,现在显示错误:

. 当我尝试使用1.7.1
版时,也发生了同样的情况。
I tried removing numpy
with: 我尝试删除numpy
:
sudo apt-get remove python-numpy
which also removed matplotlib
and scipy
. 这也删除了matplotlib
和scipy
。 So then I tried reinstalling them with: 那么我尝试重新安装它们:
sudo apt-get install python-numpy python-scipy python-matplotlib
but this fails with the error: 但这失败了,错误:
from sre_constants import *
File "/usr/local/lib/python2.7/sre_constants.py", line 18, in <module>
from _sre import MAXREPEAT
ImportError: cannot import name MAXREPEAT
Now I'm left with no running python and I don't even know how to go back to the previous stable version. 现在我没有运行python,我甚至不知道如何回到以前的稳定版本。 So the question: can I install at least version 1.7.1
in my system and if not, how do I go back to a working 1.6.0
version? 所以问题是:我可以在我的系统中安装至少版本1.7.1
,如果没有,我该如何回到工作的1.6.0
版本? Thanks. 谢谢。
sudo pip install numpy --upgrade
只需稍微努力就可以做同样的事情。
Ok, so I tried: 好的,我试过了:
pip uninstall numpy
which returned: 返回:
Successfully uninstalled numpy
So then I did: 那么我做了:
pip install numpy
but it said: 但它说:
Requirement already satisfied (use --upgrade to upgrade): numpy in /home/gabriel/.local/lib/python2.7/site-packages
Cleaning up...
so apparently it was still there. 显然它仍然在那里。 I removed the contents of that folder and then I simply did: 我删除了该文件夹的内容然后我只是做了:
sudo pip install numpy
This worked like freaking magic . 这就像怪异的魔法一样 。 Now I have NumPy 1.8.0, SciPy 0.12.0, Matplotlib 1.2.1
installed and everything is running like it should. 现在我安装了NumPy 1.8.0, SciPy 0.12.0, Matplotlib 1.2.1
,一切运行都应该如此。
