[Question] Instantiate ASR model from scratch #1586

Closed lodm94 closed 3 years ago

lodm94 commented 3 years ago

Hi all, I wish to instantiate a brand new ASR Quartznet 15x5 from a .yaml file and train it from scratch. Actually, what i'm tryin to do is what is shown in 01_ASR_with_Nemo tutorial:

first_asr_model = nemo_asr.models.EncDecCTCModel(cfg=DictConfig(params['model']), trainer=trainer)

Even just running the tutorial cell by cell, the following ValueError is returned:

num_samples should be a positive integer value, but got num_samples=0

What's wrong? I appreciate your help. Sorry if the question may sound silly. Thanks
