Deeplab V3+训练时出现的多线程问题

Question

我在训练时一直出现这个问题，在网上找到的答案说是matplotlib.pyplot造成的问题 可我在我的代码里面环境里面是有这个matplotlib包的 但是我在代码里面没找到这个包 不管是在train.py和__init__.py都没有找到这个包的导入 求大佬告知什么原因 提示错误在下面：
Traceback (most recent call last):

“RuntimeError: main thread is not in main loop“的几种解决方案_未名编程-CSDN博客 方法1最后写root.mainloop()当然，如果不是root，则应使用Tk对象的名称代替root。方法2将线程设置为守护程序t = threading.Thread(target=your_func)t.setDaemon(True)t.start() https://blog.csdn.net/qq_44275213/article/details/115773394
