+If the list of methods above are called, we should check for the `fit` or `partial_fit` methods called on the same object. 
+Or if an argument of an estimator is called and the name of the argument ends with an underscore we should check for the fit or partial_fit methods call.

+An estimator can be detected if the object inherits from `BaseEstimator`.
