Question

我正在尝试绘制一些显示here内容的大熊猫。但是每当我尝试使用以下命令按照建议设置样式选项时

pd.options.display.mpl_style = 'default'

我收到以下错误

In [6]: Traceback (most recent call last):

在处理我的测试代码时，我发现当我添加pd.options行时会生成错误。有什么理由吗？我已使用numpy

将pandas，matplotlib和pip --upgrade更新为最新版本

这与https://github.com/matplotlib/matplotlib/issues/3470的问题相同。问题在于，由于rcparams验证中的细微疏忽，macOSX后端期望成为unicode对象列表的是字节串对象列表，因此事情爆发了。

最简单的解决方法是使用除macosx后端之外的任何其他后端。正在进行补丁（https://github.com/matplotlib/matplotlib/pull/3564），但它已经变成了其他微妙错误的泥潭。

仍在尝试确定这是否需要成为1.4.1的拦截器。
