我在 Ubuntu 14.04 上安装了 Enthought Canopy。我正在尝试运行示例 matplotlib 程序(来自图书馆的网站)。每次尝试运行该程序都会使 Canopy 的命令提示符显示以下消息:
TypeError Traceback (most recent call last)

TypeError: **rc_params_from_file() got an unexpected keyword argument 'use_default_template'**
有什么解决办法吗？
最佳答案
use_default_template 关键字参数 was added到 matplotlib 版本 1.4.0rc1 中的 rc_params_from_file 函数。
很可能，您的 matplotlib 版本早于 1.4.0rc1，需要升级。
<小时/>如果您安装了多个 matplotlib，则需要确保包含较新版本的目录早于 sys.path 中的旧版本列出，或者可能只是简单地列出删除旧版本的 matplotlib。
