First time Mesa User: Can't use self.model.grid.get_neighbors over an arbitrary value.

[Jomomo05]

As shown on: https://mesa.readthedocs.io/en/latest/apis/space.html#mesa.space.MultiGrid.get_neighbors

I was trying to use

vecinos = self.model.grid.get_neighbors( (3,3) moore=True, include_center=False)
To get the neighbors over (3,3).

    But, when i try to run this code, i got multiple Tuple errors.
    
    I added "from typing import Tuple" and tried to use typing.Tuple[3,3] but it didn't work too.
    
    I am stuck and out of ideas.
    
    Any support would be appreciated.

[rht]

vecinos = self.model.grid.get_neighbors( (3,3) moore=True, include_center=False)

It looks like there is no comma in between (3,3) and moore=True? Is the typo present in the code?

[Jomomo05]

I am sorry, this typo isn't present on my code.

My code right now is:

vecinos = self.model.grid.get_neighbors( (3,3), moore=True, include_center=False)

May I know the exact error message?

[Jomomo05]

Of course.

The full error message is:

Also, i attach my ipynb.

The error happened because self.nueva_posicion is None instead of a tuple. If you handle this case in advance, there should be no problem. Make sure to also check that if self.pos != self.nueva_posicion also makes sense if it is None.
