split numpy array into train and test code example

Example 1: train_size

You have to specify this parameter only if you’re not specifying the test_size. This is the same as test_size, but instead you tell the class what percent of the dataset you want to split as the training set.

Example 2: splitting data into training and testing sklearn

train_features, test_features, train_labels, test_labels = 
train_test_split(features, labels)
#This is using sklearn
