How to Get Regression Model Summary from Scikit-Learn
WebWe build a model on the training data and test it on the test data. Sklearn provides a function train_test_split to do this task. It returns two arrays of data. Here we ask for 20% of the data in the test set. train, test = train_test_split (iris, test_size=0.2, random_state=142) print (train.shape) print (test.shape) WebAug 6, 2014 · I installed Scikit Learn a few days ago to follow up on some tutorials. I have not been able to do anything since i keep getting errors whenever i try to import anything. However when i import only the sklearn package ( import sklearn) i get no errors, its when i try to point to the modules that the errors arise. black friday deals batteries
