load_example_data('dataframe', 'admissions_train')
df = DataFrame("admissions_train")

Create a FeatureStore.

fs = FeatureStore(repo='vfs_v1', data_domain='sales')

fs.setup()

fm = fs.get_filter_manager(name='stats_filter_manager')
fm

Filter Manager 'stats_filter_manager' does not exist. Run FilterManager.load_filter() to create it.
