安装 statsmodels 时，出现以下错误:RuntimeError: 字典在迭代过程中改变了大小 [英] when installing statsmodels, I get the following error:RuntimeError: dictionary changed size during iteration

问题描述

我已经阅读了很多关于这个错误的帖子，我发布这个的原因是因为我在尝试安装 statsmodels 包时遇到了这个错误，而不是我的程序之一.

I have read a lot of posts about this error, and the reason I am posting this is because I get the error when trying to install statsmodels package, and not one of my programs.

如何在安装软件包时更正错误?

how do I correct the error when installing a package?

阅读建议的回复，我跑了:

Reading the suggested response, I ran:

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，然后再次安装时，我收到以下消息:

Uninstalled matplotlib and numpy and then upon installing it again, I get the following message:

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): python-dateutil in /usr/local/lib/python3.2/dist-packages/python_dateutil-2.2-py3.2.egg (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，重新安装会返回以下内容:

For numpy, the reinstall returns the following:

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

推荐答案

这是一个在 Python 3.* 中遇到 numpy 的错误.它似乎已在源代码中修复，但我不知道它是否已发布.

It's a bug hitting numpy in Python 3.*. It seems to have been fixed in the source, but I don't know if it has found itself to a release yet.

在安装 statsmodel 之前尝试升级 numpy.

Try upgrading numpy before installing statsmodel.

在 Python 2. 中，.keys() 函数将返回一个列表，但在 3. 中它返回一个迭代器，因此是错误的原因.

In Python 2., the .keys() function would return a list, but in 3. it returns an iterator, hence the reason to the bug.
