python - AttributeError : 'Cycler' object has no attribute 'change_key'

我正在尝试在Ubuntu上使用import matplotlib。我从源代码重新安装了matplotlib，因为我无法使用TkAgg后端。现在，我面临着一个新问题，我无法解决，也无法在任何地方找到解决方案。我正在使用Python 3.5。
运行简单导入时出现此错误，向我显示:

Traceback (most recent call last):

    cycler_inst.change_key(prop, norm_prop)
AttributeError: 'Cycler' object has no attribute 'change_key'

我认为这可能与从rcsetup.py导入循环程序有关，因为有一条评论说:

# Don't let the original cycler collide with our validating cycler

那么原始的东西与他们的骑自行车者发生了冲突吗？

我怎样才能解决这个问题？有什么建议么？谢谢!

最佳答案

刚刚检查了循环仪的版本，它已经过时了。只需更新循环器
sudo pip3 install --upgrade cycler
或者
sudo -H python3 -m pip install --upgrade cycler。
