how preprocessing voxceleb data and acc==0?

how process voxceleb data for run trian.py?

why I iter 200 using 2GPU, but acc=0?

Hi,

Got the same issue on the voxceleb_v1 dataset. I can see the loss is consistently decreasing from 7.2 to 6.01, but the eval/train accuracy is always 0.
Have you solved this?

[colinsongf]

i‘m not , sorry

[ChristopherLu]

Is this because lack of certain pre-process step for voxceleb data?

[colinsongf]

i think so, but i do not how to pre-process voxceleb data!

how to Voxceleb dataset preprocessing for dropping silence segments

@ChristopherLu @colinsongf I proprocessed voxceleb dataset to be sample rate 16,000 that is my config in default.yaml

@andabi

Could you share us the procedure to get the 'voxceleb_norm'? Is it the data after pre-processing? We are confused about the right procedures to run the code for voxceleb, it wold be great if you could share us the recipe or pipeline to achieve this.

Thanks

[andabi]

voxceleb_norm is the processed dataset. The dataset is structured to directories for each celeb. Each directory contains each celeb's wav files which have sample rate 16,000 and format is 'wav'. You need to preprocess above before training.

[colinsongf]

after processed all wav to sample rate 16,000, the result is acc=0, why?

Keep the training at least a few days because voxceleb is huge. I kept training the model a few days using 8 gpu to get over 90% eval accuracy.
