Fine-tuning Conformer
Hi,
I want to fine-tune **stt_en_conformer_ctc_large** with Persian dataset. I used **conformer_ctc_char.yaml** from your example folder in repository. I changed the labels, too. Now when I want to run **trainer.fit(asr_model)** I have the following error:
`Interpolation key 'model.encoder.d_model' not found
    full_key: optim.sched.d_model
    object_type=dict`
Would you please help me how to resolve this error?
Thanks
