我有一个代码，它将通过三个词典，如果所有键都匹配，则会作一些绘图。由于使用了matplotlib表，我遇到了一个奇怪的问题。
当我第一次运行此代码时，完成整个循环没有问题。现在第二次迭代遇到超时错误
我尝试将表移出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，以期在后端重置某些内容。

TimeoutError：锁定错误：Matplotlib无法获取以下锁定文件：C：\ Users \ myusername.matplotlib \ tex.cache \ 23c95fa5c37310802233a994d78d178d.tex.matplotlib-lock
注意：如果某些键名在此代码中不匹配，则是故意的，由于此帖子是公开的，因此我不得不对其进行更改。一旦代码到达axs.table行，第二次迭代就会引发错误。
有效的方法，但我想避免的就是删除此脚本的tex。 rc param tex设置为False，代码也很快完成了运行]
