LookupError: unknown encoding: cp0
提问by user1604594
I am on window 7, python 2.7.2, pandas 0.11.0, django 1.4, wsgi and apache 2.2. I have a pandas script that works fine if I run it directly with python and also works in ipython with %run. However, when I run pandas in my view i get "LookupError: unknown encoding: cp0". This only happens when using ols in pandas within the view. I'm also a little confused why py3compat.py is entering the picture as i'm using python 2.7. Also, I have seen some posts about wrapping a printed variable in a str(), but I'm not sure how that would apply here. The whole traceback is:
我在窗口 7、python 2.7.2、pandas 0.11.0、django 1.4、wsgi 和 apache 2.2。我有一个 Pandas 脚本，如果我直接使用 python 运行它并且在 ipython 中使用 %run 也可以正常工作。但是，当我在视图中运行 Pandas 时，我收到“LookupError: unknown encoding: cp0”。这只发生在视图中的 Pandas 中使用 ols 时。我也有点困惑为什么 py3compat.py 在我使用 python 2.7 时进入图片。另外，我看过一些关于在 str() 中包装打印变量的帖子，但我不确定这将如何应用于这里。整个回溯是：
