Breaking Changes¶

Entity.add_interesting_values has been removed. To add interesting values for a single entity, call EntitySet.add_interesting_values and pass the name of the dataframe for which to add interesting values in the dataframe_name parameter (GH#1405, GH#1370).
Entity.set_secondary_time_index has been removed and replaced by EntitySet.set_secondary_time_index with an added dataframe_name parameter to specify the dataframe on which to set the secondary time index (GH#1405, GH#1370).
Relationship initialization has been updated to accept four name values for the parent dataframe, parent column, child dataframe and child column instead of accepting two Variable objects (GH#1405, GH#1370).
EntitySet.add_relationship has been updated to accept dataframe and column name values or a Relationship object. Adding a relationship from a Relationship object now requires passing the relationship as a keyword argument (GH#1405, GH#1370).
Entity.update_data has been removed. To update the dataframe, call EntitySet.replace_dataframe and use the dataframe_name parameter (GH#1630, GH#1522).
The data in an EntitySet is no longer stored in Entity objects. Instead, dataframes with Woodwork typing information are used. Accordingly, most language referring to “entities” will now refer to “dataframes”, references to “variables” will now refer to “columns”, and “variable types” will use the Woodwork type system’s “logical types” and “semantic tags” (GH#1405).
The dictionary of tuples passed to EntitySet.__init__ has replaced the variable_types element with separate logical_types and semantic_tags dictionaries (GH#1405).
EntitySet.entity_from_dataframe no longer exists. To add new tables to an entityset, use``EntitySet.add_dataframe`` (GH#1405).
EntitySet.normalize_entity has been renamed to EntitySet.normalize_dataframe (GH#1405).
Instead of raising an error at EntitySet.add_relationship when the dtypes of parent and child columns do not match, Featuretools will now check whether the Woodwork logical type of the parent and child columns match. If they do not match, there will now be a warning raised, and Featuretools will attempt to update the logical type of the child column to match the parent’s (GH#1405).
If no index is specified at EntitySet.add_dataframe, the first column will only be used as index if Woodwork has not been initialized on the DataFrame. When adding a dataframe that already has Woodwork initialized, if there is no index set, an error will be raised (GH#1405).
Featuretools will no longer re-order columns in DataFrames so that the index column is the first column of the DataFrame (GH#1405).
Type inference can now be performed on Dask and Koalas dataframes, though a warning will be issued indicating that this may be computationally intensive (GH#1405).
EntitySet.time_type is no longer stored as Variable objects. Instead, Woodwork typing is used, and a numeric time type will be indicated by the 'numeric' semantic tag string, and a datetime time type will be indicated by the Datetime logical type (GH#1405).
last_time_index, secondary_time_index, and interesting_values are no longer attributes of an entityset’s tables that can be accessed directly. Now they must be accessed through the metadata of the Woodwork DataFrame, which is a dictionary (GH#1405).
The helper function list_variable_types will be removed in a future release and replaced by list_logical_types. In the meantime, list_variable_types will return the same output as list_logical_types (GH#1447).

What’s New in this Release¶

Adding Interesting Values

To add interesting values for a single entity, call EntitySet.add_interesting_values passing the id of the entity for which interesting values should be added.

>>> es.add_interesting_values(entity_id='log')

Setting a Secondary Time Index

To set a secondary time index for a specific entity, call EntitySet.set_secondary_time_index passing Entity for which to set the secondary time index along with the dictionary mapping the secondary time index column to the for which the secondary time index applies.

>>> customers_secondary_time_index = {'cancel_date': ['cancel_reason']}
>>> es.set_secondary_time_index(es['customers'], customers_secondary_time_index)

Creating a Relationship and Adding to an EntitySet

Relationships are now created by passing parameters identifying the entityset along with four string values specifying the parent dataframe, parent column, child dataframe and child column. Specifying parameter names is optional.

>>> new_relationship = Relationship(
...     entityset=es,
...     parent_dataframe_name='customers',
...     parent_column_name='id',
...     child_dataframe_name='sessions',
...     child_column_name='customer_id'
... )

Relationships can now be added to EntitySets in one of two ways. The first approach is to pass in name values for the parent dataframe, parent column, child dataframe and child column. Specifying parameter names is optional with this approach.

>>> es.add_relationship(
...     parent_dataframe_name='customers',
...     parent_column_name='id',
...     child_dataframe_name='sessions',
...     child_column_name='customer_id'
... )

Relationships can also be added by passing in a previously created Relationship object. When using this approach the relationship parameter name must be included.

>>> es.add_relationship(relationship=new_relationship)

Replace DataFrame

To replace a dataframe in an EntitySet with a new dataframe, call EntitySet.replace_dataframe and pass in the name of the dataframe to replace along with the new data.

>>> es.replace_dataframe(dataframe_name='log', df=df)

List Logical Types and Semantic Tags

Logical types and semantic tags have replaced variable types to parse and interpret columns. You can list all the available logical types by calling featuretools.list_logical_types.

>>> ft.list_logical_types()

You can list all the available semantic tags by calling featuretools.list_semantic_tags.

>>> ft.list_semantic_tags()

Breaking Changes¶

Calls to featuretools.dfs or featuretools.calculate_feature_matrix that use a cutoff time dataframe, but do not label the time column with either the target entity time index variable name or as time, will now result in an AttributeError. Previously, the time column was selected to be the first column that was not the instance id column. With this update, the position of the column in the dataframe is no longer used to determine the time column. Now, both instance id columns and time columns in a cutoff time dataframe can be in any order as long as they are named properly.
The type_string attributes of all Variable subclasses are now a snake case conversion of their class names. This changes the type_string of the Unknown, IPAddress, EmailAddress, SubRegionCode, FilePath, LatLong, and ZIPcode classes. Old saved entitysets that used these variables may load incorrectly.

Thanks to the following people for contributing to this release: @frances-h, @gsheni, @jeff-hernandez, @rwedge

Breaking Changes¶

Using training windows in feature calculations can result in different values than previous versions. This was done to prevent consecutive training windows from overlapping by excluding data at the oldest point in time. For example, if we use a cutoff time at the first minute of the hour with a one hour training window, the first minute of the previous hour will no longer be included in the feature calculation.

v0.13.4 Mar 27, 2020¶

Thanks to the following people for contributing to this release: @frances-h, @jeff-hernandez, @rwedge, @systemshift

Breaking Changes¶

The libraries used for downloading or uploading from S3 or URLs are now optional and will no longer be installed by default. To use this functionality they will need to be installed separately.

Breaking Changes¶

ft.dfs now has a groupby_trans_primitives parameter that DFS uses to automatically construct features that group by an ID column and then apply a transform primitive to search group. This change applies to the following primitives: CumSum, CumCount, CumMean, CumMin, and CumMax.
Previous behavior
ft.dfs(entityset=es, target_entity='customers', trans_primitives=["cum_mean"])
New behavior
ft.dfs(entityset=es, target_entity='customers', groupby_trans_primitives=["cum_mean"])

Related to the above change, cumulative transform features are now defined using a new feature class, GroupByTransformFeature.
