Breaking Changes

  • :pr:1100: The behavior for init has changed. A full schema is a schema that contains all of the columns of the dataframe it describes whereas a partial schema only contains a subset. A full schema will also require that the schema is valid without having to make any changes to the DataFrame. Before, only a full schema was permitted by the init method so passing a partial schema would error. Additionally, any parameters like logical_types would be ignored if passing in a schema. Now, passing a partial schema to the init method calls the init_with_partial_schema method instead of throwing an error. Information from keyword arguments will override information from the partial schema. For example, if column a has the Integer Logical Type in the partial schema, it's possible to use the logical_type argument to reinfer it's logical type by passing {'a': None} or force a type by passing in {'a': Double}. These changes mean that Woodwork init is less restrictive. If no type inference takes place and no changes are required of the DataFrame at initialization, init_with_full_schema should be used instead of init. init_with_full_schema maintains the same functionality as when a schema was passed to the old init.

Breaking Changes

  • :pr:`1065`: The criteria for categorical type inference have changed. Relatedly, the meaning of both the categorical_threshold and numeric_categorical_threshold settings have changed. Now, a categorical match is signaled when a series either has the "categorical" pandas dtype or if the ratio of unique value count (nan excluded) and total value count (nan also excluded) is below or equal to some fraction. The value used for this fraction is set by the categorical_threshold setting which now has a default value of 0.2. If a fraction is set for the numeric_categorical_threshold setting, then series with either a float or integer dtype may be inferred as categorical by applying the same logic described above with the numeric_categorical_threshold fraction. Otherwise, the numeric_categorical_threshold setting defaults to None which indicates that series with a numerical type should not be inferred as categorical. Users who have overridden either the categorical_threshold or numeric_categorical_threshold settings will need to adjust their settings accordingly.
  • :pr:`1083`: The process of sampling series for logical type inference was updated to be more consistent. Before, initial sampling for inference differed depending on collection type (pandas, dask, or koalas). Also, further randomized subsampling was performed in some cases during categorical inference and in every case during email inference regardless of collection type. Overall, the way sampling was done was inconsistent and unpredictable. Now, the first 100,000 records of a column are sampled for logical type inference regardless of collection type although only records from the first partition of a dask dataset will be used. Subsampling performed by the inference functions of individual types has been removed. The effect of these changes is that inferred types may now be different although in many cases they will be more correct.

v0.3.1 May 12, 2021

Warning

This Woodwork release uses a weak reference for maintaining a reference from the accessor to the DataFrame. Because of this, chaining a Woodwork call onto another call that creates a new DataFrame or Series object can be problematic.

Instead of calling pd.DataFrame({'id':[1, 2, 3]}).ww.init(), first store the DataFrame in a new variable and then initialize Woodwork:

df = pd.DataFrame({'id':[1, 2, 3]})
df.ww.init()
