TypeError: fit() missing 1 required positional argument: 'y'
Whenever you try to initialize/ define an object of a class you must call its own constructor to create one object for you. The constructor may have parameters or none. In your case GaussianNB is a class from sklearn which has a non-parametric constructor by default.
obj_model = GaussianNB()So simply we do create an object with empty parenthesis which simply means default constructor.
You forgot to put () after your model, gaussianNB.Try doing this in line 6:
model = GaussianNB()I am pretty sure it will solve the problem.
