set_features_inactive

Use set_feature_inactive() to mark the Feature status as inactive. If a Feature is inactive, then it won't be part of any further processing. Setting a Feature to Active includes it in processing again.

Example:

>>> from teradataml import DataFrame, DataSource, FeatureStore, load_example_data

# Create DataFrame on admissions data.
>>> df = DataFrame("admissions_train")
>>> df
   masters   gpa     stats programming  admitted

set_features_active

Use set_features_active() to mark the status of a Feature as active.

# Mark Feature 'programming' from 'inactive' to 'active'.
>>> fs.set_features_active('programming')

# Get FeatureGroup again after setting feature active.
>>> fg = fs.get_feature_group('admissions')
>>> fg
FeatureGroup(admissions, features=[Feature(name=masters), Feature(name=programming), Feature(name=admitted), Feature(name=stats), Feature(name=gpa)], entity=Entity(name=admissions), data_source=DataSource(name=admissions))
