在 matplotlib for 循环中间遇到超时错误

Question

我有一个代码可以遍历三个词典，如果所有键都匹配则绘制一些图。由于使用了 matplotlib table.

，我运行遇到了一个奇怪的问题

当我第一次将此代码转为运行时，我在完成整个循环时没有遇到任何问题。现在我在第二次迭代时遇到超时错误

我尝试将 table 移出 for 循环。我添加了 plt.close('all') 我还尝试在循环结束时再次导入 matplotlib，希望在后端重置一些东西。

TimeoutError: Lock error: Matplotlib 获取以下锁文件失败： C:\Users\myusername.matplotlib\tex.cachec95fa5c37310802233a994d78d178d.tex.matplotlib-锁

注意：如果某些键名在此代码中不匹配，那是故意的，我必须为此 post 更改它们，因为它是 public。一旦代码到达 axs.table 行，第二次迭代就会抛出错误。

Answer 1

在使用 conda 命令提示符清理环境后，我运行得到了所有内容

conda clean --all

一些有用但我想避免的东西只是删除了这个脚本的 tex 的使用。 rc param tex 设置为 False，代码也很快完成运行ning
