Python - mesa：如何獲取每個對象的實例變量

Question

我正在爲我的程序使用mesa。我試圖執行我的模型類，但我從代理類中得到了AttributeError。

這是我的腳本：

class ComtrModel (Model): 
    """ A model with some number of Agents""" 
    def __init__(self,N): 
     self.num_agents = N 
     self.schedule = RandomActivation(self) 
     for i in range (N): 
      a = CommuterAgent(i) 
      self.schedule.add(a) 

class CommuterAgent (Agent): 
    def __init__(self, model): 
     self.famsize = famsize 
     self.distance = distance 
     self.update_need = None 


    def step(self): 
     if self.distance >= 10000: 
      self.update_need = self.update_need() 
      return 

    def update_need (self, famsize): 
     if self.famsize : 
      self.famsize = famsize 
      return 
      prob_need() 

如何獲得每個代理的變量？我需要檢查它以確保模型正常運行。

到目前爲止，這是我的代碼執行（在交互式會話）：

from src.ComtrModel import * 
model = ComtrModel(5) 
for i in range (10): 
    model.step() 

for key, value in CommuterAgent.step(model): 
    print(key, value) 

編輯：但它返回

Traceback (most recent call last): 
    File "C:src/__init__.py", line 3, in <module> 
    from src.ComtrModel import * 
    File "C:\src\__init__.py", line 9, in <module> 
    for key, value in CommuterAgent.step(model): 
    File "C:\src\ComtrModel.py", line 40, in step 
    if self.distance >= 10000: 
AttributeError: 'ComtrModel' object has no attribute 'distance' 

我也試過這樣的事情：

>>> hi_obj = hi() 
>>> hi_obj.__dict__.keys() 

但它只適用於單個物體

Answer 1

def __init__(self, model): 
     self.famsize = famsize 
     self.distance = distance 
     self.update_need = None 

看起來不正確。您不會將famsize和distance作爲參數傳遞。
