我正在尝试在由yerevann实现的Theano中实现动态内存网络。 链接到该代码-https://github.com/YerevaNN/Dynamic-memory-networks-in-Theano。
执行下面同样编写的main.py文件后，出现此错误： “发生了异常，请使用％tb查看完整的追溯。
SystemExit：2英寸

SystemExit：2

有人可以告诉我此异常是什么意思吗？
答案 0 :(得分：0)
args = parser.parse_args()与Jupyter Notebook有冲突。
您可以使用python filename.py来运行这些代码。
或者您可以使用
class Args(dict):
__setattr__ = dict.__setitem__
__getattr__ = dict.__getitem__
args = {
'output_dir' : None
'seed' : 42
}
args = Args(args) # dict2object
obj = args.copy() # object2dict
替换jupyter笔记本中的args（仅用于测试）
