Program KeyError

[TYoung1221]

您好，当我输入例子，例如example/2.jpg，example/5.jpg，和hard下的例子，都会报一个status错误。
` 68 # print(parser_tree)
69 set_forward_step(0)
---> 70 post_order(parser_tree)
71 y_start = 0.9
72 y_stride = 0.2

~/Desktop/dino/mathAI/code/calculator/init.py in post_order(node)
275 elif node['type'] == NODE_TYPE['e']:
276 # print('post_order e')
--> 277 t = post_order(child[0])
278 node['status'] = child[0]['status']
279 node['value'] = child[0]['value']

~/Desktop/dino/mathAI/code/calculator/init.py in post_order(node)
199 # print('post_order t',child[0])
200 f = post_order(child[0])
--> 201 node['status'] = child[0]['status']
202 node['value'] = child[0]['value']
203 latex_str = f

KeyError: 'status'

你好，现在只能跑简单版本的加减乘数运算，复杂的不公开。
