I try to use Pyannotes models offline.

I was loading and applying models like this:

from pyannote.audio import Pipeline

access_token = 'xxxxxxxxxxx'

model = Pipeline.from_pretrained(
         "pyannote/speaker-diarization-3.1",
         use_auth_token=access_token)

path_in = 'blabla/1-137-A-32.wav'

num_speakers = 1

model(path_in,
   num_speakers=num_speakers).labels()

That works fine.

But now I followed the instructions for offline use: https://github.com/pyannote/pyannote-audio/blob/develop/tutorials/applying_a_pipeline.ipynb

My directory structure is as follows:

src-
     |-pyannote_offline_config.yaml
     |-pyannote_pytorch_model.bin

—- YAML —-

version: 3.1.0

pipeline:
  name: pyannote.audio.pipelines.SpeakerDiarization
  params:
    clustering: AgglomerativeClustering
    embedding: pyannote/wespeaker-voxceleb-resnet34-LM
    embedding_batch_size: 32
    embedding_exclude_overlap: true
    segmentation: src/pyannote_pytorch_model.bin
    segmentation_batch_size: 32

params:
  clustering:
    method: centroid
    min_cluster_size: 12
    threshold: 0.7045654963945799
  segmentation:
    min_duration_off: 0.0

—- Loading Model —-

path_yaml = 'src/pyannote_offline_config.yaml'

model = Pipeline.from_pretrained(path_yaml)

path_in = 'blabla/1-137-A-32.wav'

num_speakers = 1

model(path_in,
         num_speakers=num_speakers).labels()

But that results in: “A pipeline must be instantiated with pipeline.instantiate(parameters) before it can be applied.”

OK, next try:

—- Loading Model —-

path_yaml = 'src/pyannote_offline_config.yaml'

model = Pipeline.from_pretrained(path_yaml)

params = {'clustering':
    {'method': 'centroid',
    'min_cluster_size': 12,
    'threshold': 0.7045654963945799},
  'segmentation':
    {'min_duration_off': 0.0}}


pipeline = model.instantiate(params)

path_in = 'blabla/1-137-A-32.wav'

num_speakers = 1

pipeline(path_in,
         num_speakers=num_speakers).labels()

But that results in: “A pipeline must be instantiated with pipeline.instantiate(parameters) before it can be applied.”

I don’t understand the problem.
