安装statsmodels的时候，我得到以下错误：RuntimeError：字典迭代过程中更改大小(

我已经阅读了很多关于这个错误的帖子，和我张贴这种情况的原因是因为我试图安装statsmodels包时得到的错误，而不是我的计划之一。

如何安装一个包，当我纠正错误？

Cleaning up...
Command python setup.py egg_info failed with error code 1 in /tmp/pip_build_root/statsmodels

读建议的反应，我跑：

sudo pip3 install numpy --upgrade
Requirement already up-to-date: numpy in /usr/local/lib/python3.2/dist-packages
Cleaning up...

卸载matplotlib和numpy的，然后在重新安装它，我得到以下信息：

sudo pip3 install matplotlib
Requirement already satisfied (use --upgrade to upgrade): matplotlib in /usr/local/lib/python3.2/dist-packages
Requirement already satisfied (use --upgrade to upgrade): numpy>=1.5 in /usr/lib/python3/dist-packages (from matplotlib)

Requirement already satisfied (use --upgrade to upgrade): tornado in /usr/local/lib/python3.2/dist-packages (from matplotlib)

Requirement already satisfied (use --upgrade to upgrade): six in /usr/local/lib/python3.2/dist-packages/six-1.7.2-py3.2.egg (from python-dateutil->matplotlib)
Cleaning up...

对于numpy的，重新安装返回以下内容：

sudo pip3 install numpy
Requirement already satisfied (use --upgrade to upgrade): numpy in /usr/lib/python3/dist-packages
Cleaning up..

Answer 1:

这是打在Python 3 numpy的一个bug *。 这似乎已经固定在来源，但我不知道，如果它发现自己的版本呢。

尝试安装statsmodel之前升级numpy的。

在Python 2 中，.keys（）函数会返回一个列表，但在3它返回一个迭代器，因此有理由的bug。
