Issue description

I wanted to improve my segmentation with Pyannote, since most of my segments are very long when the same person is talking. Since min_duration_off is already set to 0.0, I looked through the code and found the classes Resegmentation and AdaptiveVoiceActivityDetection.

I thought by applying one of those methods I would be able to get shorter segments, however it seems the code is not working. Is this legacy code or should it work?

For AdaptiveVoiceActivityDetection I get the error:

  File "/home/.../PycharmProjects/..../venv/lib/python3.10/site-packages/pyannote/audio/pipelines/voice_activity_detection.py", line 313, in apply
    vad_pipeline = VoiceActivityDetection("vad").instantiate(
  File "/home/.../PycharmProjects/..../venv/lib/python3.10/site-packages/pyannote/audio/pipelines/voice_activity_detection.py", line 123, in __init__
    model = get_model(segmentation, use_auth_token=use_auth_token)
  File "/home/.../PycharmProjects/.../venv/lib/python3.10/site-packages/pyannote/audio/pipelines/utils/getter.py", line 89, in get_model
    model.eval()
AttributeError: 'NoneType' object has no attribute 'eval'

Could not download 'vad' model.

I initialize the model like this:

self.vad = AdaptiveVoiceActivityDetection(MODEL_PATH_SEG)
self.vad.instantiate({"num_epochs": 1, "batch_size": settings.BATCH_SIZE_SEG, "learning_rate": 0.1})
self.vad.to(self.device)
#call
va = self.vad(tensor_audio_mapping)

For me it seems to be like the instantiation is hardcoded (line 313) and the model key "vad" can not be found?

For Resegmentation I get the error, however I can not see what is wrong my way of instantion since it works, for example in case of SpeakerDiarization:

  File "/home/.../PycharmProjects/.../pyannote_service.py", line 125, in diarize
    reseg = self.resegmentation_model(file=tensor_audio_mapping, diarization=diarization)
  File "/home/.../PycharmProjects/.../venv/lib/python3.10/site-packages/pyannote/audio/core/pipeline.py", line 304, in __call__
    raise RuntimeError(
RuntimeError: A pipeline must be instantiated with `pipeline.instantiate(parameters)` before it can be applied.

I initialize the model like this:

 self.resegmentation_model = Resegmentation(segmentation=MODEL_PATH_SEG)
 self.resegmentation_model.instantiate(co["params"])
 self.resegmentation_model.to(self.device)
# diarization is the diarization object produced by a speaker_d pipeline from pyannote
reseg = self.resegmentation_model(file=tensor_audio_mapping, diarization=diarization)

where co refers to a yaml which looks like this:

version: 3.1.0
pipeline:
  name: pyannote.audio.pipelines.SpeakerDiarization
  params:
    clustering: AgglomerativeClustering
    embedding: models/pyannote/pyannote_embedding.bin
    embedding_batch_size: 32
    embedding_exclude_overlap: true
    segmentation: models/pyannote/pyannote_segmentation.bin
    segmentation_batch_size: 32

params:
    min_duration_off: 0.0

Would appreciate any insights I might have missed out on or just a short clarification if the code is not intended for usage.

Okay for the Resegmentation pipeline it seems to be that it does not work with pyannote/segmentation-3.0. But it does work with pyannote/segmentation, which unfortunately gives me a a few warnings:

Just wanted to let you know.
