AttributeError: 'Annotation' object has no attribute 'for_json'

This was tried on Jupyter Notebook on local device as well as on Google Collab. The error remains the same.

Minimal reproduction example (MRE)

AttributeError: 'Annotation' object has no attribute 'for_json'

Looks like a problem with speechbox, not ˋpyannote.audio`.

[alvynabranches]

What is the fix?

[hbredin]

There is indeed no function for_json in pyannote.core. The code calling for_json is in speechbox (line 90 of file speechbox/diarize.py) , not pyannote. Closing.
