Serialization

pyannote.core.json provides convenient functions to (de)serialize pyannote.core data structure instances to (from) JSON.

In [14]: from pyannote.core import Segment, Timeline, Annotation

In [13]: import pyannote.core.json

In [15]: pyannote.core.json.dumps(Segment(0, 1))
Out[15]: '{"start": 0, "end": 1}'

In [16]: timeline = Timeline([Segment(0, 1), Segment(1, 3)], uri='my_file')

In [22]: serialized = pyannote.core.json.dumps(timeline)

In [23]: deserialized = pyannote.core.json.loads(serialized)

In [24]: deserialized == timeline
Out[24]: True
