Python pandas stuck at version 0.7.0
提问by James Haskell
First off, I'm a novice... I'm a newbie to Python, pandas, and Linux.
首先，我是新手……我是 Python、pandas 和 Linux 的新手。
I'm getting some errors when trying to populate a DataFrame (sql.read_frame() gives an exception when trying to read from my MySQL DB, but I am able to execute and fetch a query / stored proc). I noticed that pandas is at version 0.7.0, and running "sudo apt-get install python-pandas" just says that it's up to date (no errors): "... python-pandas is already the newest version. 0 upgraded..."
尝试填充 DataFrame 时出现一些错误（sql.read_frame() 在尝试从我的 MySQL 数据库中读取时出现异常，但我能够执行和获取查询/存储过程）。我注意到pandas的版本是0.7.0，运行“sudo apt-get install python-pandas”只是说它是最新的（没有错误）：“... python-pandas已经是最新版本。0升级……”
Based on some other posts I found on the web, I think my DataFrame problem may be due to the older version of pandas (something about a pandas bug involving tuples of tuples?). Why won't pandas update to a more current version?
根据我在网上找到的其他一些帖子，我认为我的 DataFrame 问题可能是由于旧版本的 Pandas（关于 Pandas 错误涉及元组元组？）。为什么大Pandas不会更新到更新的版本？
Setup:
设置：
Ubuntu: 12.04.2 LTS Desktop (virtual workstation on VMWare)
sudo apt-get update, sudo apt-get upgrade, and sudo apt-get dist-upgrade all current
Python: 2.7.3 (default, April 10 2013, 06:20:15) /n [GCC 4.6.3] on Linux2
$ "which python" only show a single instance: /usr/bin/python
pandas.__version__ = 0.7.0
numpy.__version__ = 1.6.1
I tried installing Anaconda previously, but that turned into a big nightmare, with conflicting versions of Python. I finally rolled back to previous VM snapshot and started over, installing all of the MySQL, pandas, and iPython using apt-get on the individual packages.
我之前尝试过安装 Anaconda，但这变成了一场大噩梦，因为 Python 版本相互冲突。我终于回滚到以前的 VM 快照并重新开始，使用 apt-get 在各个包上安装所有 MySQL、pandas 和 iPython。
I'm not having any other problems on this workstation... apt-get seems to be working fine in general, and all other apps (MySQL Workbench, Kettle / spoon, etc.) are all working properly and up to date.
我在这个工作站上没有任何其他问题... apt-get 似乎总体上运行良好，并且所有其他应用程序（MySQL Workbench、Kettle/spoon 等）都正常运行并且是最新的。
Any ideas why Python pandas won't upgrade to 0.11.0? Thank you.
为什么 Python pandas 不会升级到 0.11.0 的任何想法？谢谢你。

As nitin points out, you can simply upgrade pandas using pip:
正如 nitin 指出的，您可以简单地使用 pip 升级 Pandas：
pip install --upgrade pandas
Since this version of pandas will be installed in site-packagesyou will, in fact, be at the mercy of any automatic updates to packages within that directory. It's wise to install the versions of packages you want into a virtual environmentso you have a consistent working environment with the bonus of reproducibility.
由于此版本的 pandas 将安装在site-packages您中，实际上，您将受到对该目录中软件包的任何自动更新的支配。明智的做法是将您想要的软件包版本安装到虚拟环境中，这样您就有了一致的工作环境和可重复性的好处。
To answer your last question, the reason Pandas won't "upgrade" to 0.11.0 using apt-get updateis that packages (of Pandas) from your distribution lag behind or haven't been created yet.
为了回答您的最后一个问题，Pandas 不会使用“升级”到 0.11.0 的原因apt-get update是您的发行版中的包（Pandas）滞后或尚未创建。

"pip install --upgrade pandas" did not work for me on a fresh Ubuntu: 12.04.2 LTS Desktop instance. Within Python, pandas was still showing version 0.7.0.
“pip install --upgrade pandas”在全新的 Ubuntu: 12.04.2 LTS 桌面实例上对我不起作用。在 Python 中，pandas 仍然显示版本 0.7.0。
Instead, I was able to get the update through by using easy install:
相反，我能够通过使用简单安装来获得更新：
sudo easy_install -U pandas

Try upgrading with pip, like so
尝试使用 pip 升级，就像这样
pip install --upgrade pandas
