从_file（）导入Canopy rc_params_中的matplotlib时出错

Question

我已经在我的ubuntu14.04上安装了热情的顶篷。我试着运行matplotlib示例程序（从图书馆的网站）。每次尝试运行该程序时，驾驶舱的命令提示符会显示以下消息：

TypeError                                 Traceback (most recent call last)

TypeError: **rc_params_from_file() got an unexpected keyword argument 'use_default_template'** 

有什么办法解决吗？在

Answer 1

使用Canopy包管理器将matplotlib更新到最新版本。在

Answer 2

matplotlib版本1.4.0rc1中rc_params_from_file函数的use_default_template关键字参数was added。在

很可能，您的matplotlib版本早于1.4.0rc1，需要升级。在

如果安装了多个matplotlib安装，则需要确保包含较新版本的目录在sys.path中早于旧版本，或者，只需删除较旧版本的matplotlib。在
