speechbrain/spkrec-ecapa-voxceleb · missing `mean_norm

Feb 18

When i run:

emb_model = EncoderClassifier.from_hparams(source="speechbrain/spkrec-ecapa-voxceleb")

i get this:

When i go to hyperparams.yaml, i have this in modules and pretainer:

# ...
modules:
    compute_features: !ref <compute_features>
    mean_var_norm: !ref <mean_var_norm>
    embedding_model: !ref <embedding_model>
    mean_var_norm_emb: !ref <mean_var_norm_emb>
    classifier: !ref <classifier>

pretrainer: !new:speechbrain.utils.parameter_transfer.Pretrainer
    loadables:
        embedding_model: !ref <embedding_model>
        mean_var_norm_emb: !ref <mean_var_norm_emb>
        classifier: !ref <classifier>
        label_encoder: !ref <label_encoder>
    paths:
        embedding_model: !ref <pretrained_path>/embedding_model.ckpt
        mean_var_norm_emb: !ref <pretrained_path>/mean_var_norm_emb.ckpt
        classifier: !ref <pretrained_path>/classifier.ckpt
        label_encoder: !ref <pretrained_path>/label_encoder.txt

Shouldn't it have a loadble for mean_var_norm and a mean_var_norm.ckpt?

I am new into the speechbrain/huggingface community and trying to understand how this repo works.
Thanks for your attention.

Hello,

Any news regarding this issue please?

Thanks.

The settings for the mean and variance normalization are the following:

mean_var_norm: !new:speechbrain.processing.features.InputNormalization
    norm_type: sentence
    std_norm: False

Which results in a parameter-free normalization, i.e. each sentence is normalized independently from the others. Nothing has to be loaded in order for it to work properly.
