                ----------
                inputs : dict
                    input `event_data` should point to a `Readable` object containing
                    the 'json' formatted event data. input `lineup_data` should point
                    to a `Readable` object containing the 'json' formatted lineup data.
                options : dict
                    Options for deserialization of the StatsBomb file. Possible options are
                    `event_types` (list of event types) to specify the event types that
                    should be returned. Valid types: "shot", "pass", "carry", "take_on" and
                    "generic". Generic is everything other than the first 4. Those events
                    are barely parsed. This type of event can be used to do the parsing
                    yourself.
                    Every event has a 'raw_event' attribute which contains the original
                    dictionary.

                ----------
                inputs : dict
                    input `raw_data` should point to a `Readable` object containing
                    the 'json' formatted event data. input `metadata` should point
                    to a `Readable` object containing the `xml` metadata file.
                options : dict
                    Options for deserialization of the Metrica Sports event json file. 
                    Possible options are `event_types` (list of event types) to specify 
                    the event types that should be returned. Valid types: "shot", "pass", 
                    "carry", "take_on" and "generic". Generic is everything other than 
                    the first 4. Those events are barely parsed. This type of event can 
                    be used to do the parsing yourself.
                    Every event has a 'raw_event' attribute which contains the original
                    dictionary.

                Parameters
                ----------
                inputs : dict
                    input `event_data` should point to a `Readable` object containing
                    the 'json' formatted event data. input `lineup_data` should point
                    to a `Readable` object containing the 'json' formatted lineup data.
                options : dict
                    Options for deserialization of the StatsBomb file. Possible options are
                    `event_types` (list of event types) to specify the event types that
                    should be returned. Valid types: "shot", "pass", "carry", "take_on" and
                    "generic". Generic is everything other than the first 4. Those events
                    are barely parsed. This type of event can be used to do the parsing
                    yourself.
                    Every event has a 'raw_event' attribute which contains the original
                    dictionary.

                Deserialize Opta event data into a `EventDataset`.

                Parameters
                ----------
                inputs : dict
                    input `f24_data` should point to a `Readable` object containing
                    the 'xml' formatted event data. input `f7_data` should point
                    to a `Readable` object containing the 'xml' formatted f7 data.
                options : dict
                    Options for deserialization of the Opta file. Possible options are
                    `event_types` (list of event types) to specify the event types that
                    should be returned. Valid types: "shot", "pass", "carry", "take_on" and
                    "generic". Generic is everything other than the first 4. Those events
                    are barely parsed. This type of event can be used to do the parsing
                    yourself.
                    Every event has a 'raw_event' attribute which contains the original
                    dictionary.

                Deserialize Opta event data into a `EventDataset`.

                Parameters
                ----------
                inputs : dict
                    input `f24_data` should point to a `Readable` object containing
                    the 'xml' formatted event data. input `f7_data` should point
                    to a `Readable` object containing the 'xml' formatted f7 data.
                options : dict
                    Options for deserialization of the Opta file. Possible options are
                    `event_types` (list of event types) to specify the event types that
                    should be returned. Valid types: "shot", "pass", "carry", "take_on" and
                    "generic". Generic is everything other than the first 4. Those events
                    are barely parsed. This type of event can be used to do the parsing
                    yourself.
                    Every event has a 'raw_event' attribute which contains the original
                    dictionary.
