Heya all I am reading some source code and the opening lines don't seem to running well.
from abc import abstractmethod
from scipy.stats import multivariate_normal
from ..base import Base, Property
from .kalman import KalmanUpdater
from ..types.update import GaussianMixtureUpdate
from ..types.state import TaggedWeightedGaussianState
from ..types.numeric import Probability
We are using a library called stonesoup. What do the .. mean before importing?
I get the errors: ImportError: attempted relative import with no known parent package
