Question

我有一台新的笔记本电脑（macOS 10.14），并已对其进行设置以进行计算。我已经使用Macports安装python和pip，并且一直在使用pip添加python包。我用pip安装了matplotlib：

pip install --user matplotlib

这似乎很好用，但是现在每当我导入pyplot时，我都会得到这个奇怪的输出：

}

它似乎没有影响代码输出，但是很烦人并且有些难看。为什么会出现此输出，如何停止它？（到目前为止）其他任何python模块都不会发生。我是pip的新手，这是否表明我在安装过程中做错了什么？谢谢！

使用matplotlib导入pyplot时输出奇怪
