【问题描述】：
我一直在两台不同的计算机上处理我的代码，使用 git 存储库提交所有更改。
最近我遇到了一个奇怪的问题，当使用 figurecanvasTkagg.draw() 时，我总是在一台计算机上得到 ZeroDivisionError，而另一台计算机运行正常并执行代码直至完成。
它具体说它在 matplotlib/_layoutgrid.py 的 grid_constraints 方法中执行 h0 = h / self.height_ratios[0] 时崩溃
实际上我无法更改任何内容，因为此方法就在库中，而且我找不到访问或修改它的方法。我已经尝试搜索几天来解决此错误，但我一无所获。
这是我在执行 draw() 函数时收到的消息错误：
