在Canopy中导入matplotlib时出错 - rc_params_from_file（）

Question

我在Ubuntu 14.04上安装了Enthought Canopy。我试图运行示例matplotlib程序（从图书馆的网站）。运行程序的每一个试图让下面的消息雨棚的命令提示符显示：

TypeError         Traceback (most recent call last)

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

任何想法如何解决呢？

Answer 1

use_default_template关键字参数was added添加到matplotlib版本1.4.0rc1中的rc_params_from_file函数。

很可能，您的matplotlib版本比1.4.0rc1旧，需要升级。

如果您安装matplotlib的多于一个的安装，你需要确保包含新版本的目录早于旧版本列在sys.path，或者，干脆删除旧版本matplotlib。

Answer 2

使用Canopy Package Manager将matplotlib更新到最新版本。
