Matplotlib AttributeError:模块“matplotlib.cbook"没有属性“_define_aliases" [英] Matplotlib AttributeError: module 'matplotlib.cbook' has no attribute '_define_aliases'

问题描述

尝试使用 pyplot 在 jupyter 上绘制图形时，我正在运行以下代码:

When trying to plot a graph on jupyter with pyplot I am running the following code:

import matplotlib.pyplot as plt
plt.plot([1,2,3,4])
plt.ylabel('some numbers')
plt.show()

这将返回以下错误:

我的 matplotlib 在没有 jupyter 的情况下一直运行良好.从那以后，我再次尝试完全重新安装 matplotlib、jupyter 和 python，但仍然遇到相同的错误.也许有人有同样的问题?

My matplotlib has always worked fine without the jupyter. I have tried a complete reinstall of matplotlib, jupyter and python again since but still getting the same error. Maybe someone had the same problem?

推荐答案

我遇到了这个确切的错误.问题是 matplotlib 的 2 个包分别由 conda 和 pip 安装

I had this exact error .The problem was that 2 packages of matplotlib was installed one by conda and one by pip

要对此进行测试:

$ conda list matplotlib

matplotlib 2.0.2 np113py35_0matplotlib 2.1.1

matplotlib 2.0.2 np113py35_0 matplotlib 2.1.1

问题！修复:

$ pip 卸载 matplotlib

强制 matplotlib 升级到 pip 想要的版本可能是个好主意:

Probably a good idea to force matplotlib upgrade to the version pip wanted:

$ conda install matplotlib=2.1.1
