TimeSeriesDataFrame.from_data_frame#

classmethod TimeSeriesDataFrame.from_data_frame(df: DataFrame, id_column: Optional[str] = None, timestamp_column: Optional[str] = None) → TimeSeriesDataFrame[source]#

Construct a TimeSeriesDataFrame from a pandas DataFrame.

Parameters

  • df (pd.DataFrame) –

    A pd.DataFrame with ‘item_id’ and ‘timestamp’ as columns. For example:

       item_id  timestamp  target
0        0 2019-01-01       0
1        0 2019-01-02       1

8        2 2019-01-03       8

  • id_column (str) – Name of the ‘item_id’ column if column name is different

  • timestamp_column (str) – Name of the ‘timestamp’ column if column name is different

Returns

ts_df – A data frame in TimeSeriesDataFrame format.

Return type

TimeSeriesDataFrame
