概述

当我试图通过代码绘制交互式绘图时：

import matplotlib.pyplot as plt
import PyQt5
%matplotlib qt
...
plt.plot(a_list,b_list)
plt.show()

我收到以下错误消息：

我在Windows电脑上使用jupyter笔记本.使用％matplotlib内联,一切正常,并生成内联图片,但使用％matplotlib qt,它不是.

%matplotlib qt5

总结

以上是编程之家为你收集整理的python – TypeError：__ init __()缺少1个必需的位置参数：’figure’全部内容，希望文章能够帮你解决python – TypeError：__ init __()缺少1个必需的位置参数：’figure’所遇到的程序开发问题。
