I'm trying to complete the Mesa tutorial (https://media.readthedocs.org/pdf/mesa/latest/mesa.pdf) and am running into repeated attribute errors.

I just tried this code (exactly as it's printed in the tutorial):

import random

from mesa import Agent, Model

from mesa.time import RandomActivation

from mesa.space import MultiGrid



class MyAgent(Agent):

    def __init__(self, name, model):

        super().__init__(name, model)

    def step(self):

        print("{} activated".format(self.name))



class MyModel(Model):

    def __init__(self, n_agents):

        self.schedule = RandomActivation(self)

        self.grid = MultiGrid(10, 10, torus=True)

        for i in range(n_agents):

            a = MyAgent(i, self)

            self.schedule.add(a)

            coords = (random.randrange(0, 10), random.randrange(0, 10))

            self.grid.place_agent(a, coords)

    def step(self):

        self.schedule.step()

I ran it like so:

model = MyModel(5)

model.step()

And ended up getting the following error:
Traceback (most recent call last):

File "", line 2, in
model.step()

File "", line 11, in step
self.schedule.step()

File "/anaconda3/lib/python3.6/site-packages/mesa/time.py", line 113, in step
agent.step()

File "", line 5, in step
print("{} activated".format(self.name))

AttributeError: 'MyAgent' object has no attribute 'name'

I've looked at a number of postings dealing with attribute errors and none of them seem to be applicable to whatever is going on here. Any suggestions?

Thanks!
