解决python多线程报错:AttributeError: Cant pickle local object问题

报错信息： Traceback (most recent call last): File “D:/flaskProject/test.py”, line 35, in test pool.apply(self.out, args=(i,)) File “Python37-32\lib\multiprocessing\pool.py”, line 261, in apply return self.apply_async(func, args, kwds).get() File “\lib\multiprocessing\pool.py”, line 657, in get raise se

这个错误通常是由于Python的多进程模块（如multiprocessing）无法序列化函数导致的。解决方法是将该函数定义在可导入的模块中，而不是在主程序中。您可以将`face_recognize`函数定义在一个单独的.py文件中，并使用`import`语句将其导入到主程序中。这样就可以避免`Can't pickle`错误了。
