1 出现该异常的原因是pickle模块不能序列化lambda function.查看下面的链接可知pickle模块可序列那些类型
https://docs.python.org/3/library/pickle.html#what-can-be-pickled-and-unpickled
2 解决方案
https://github.com/uqfoundation/dill 使用pickle的替代者
3 使用demo
import dill
if __name__ == "__main__":
s = dill.dumps(lambda x, y: x+y)
f = dill.loads(s)
assert f(3,4) == 7
