fastpitch+hifigan inference throws error

I tried inferencing on waveglow and it worked fine but on hifigan with the nvidia provided checkpoints it has been throwing the following error
Traceback (most recent call last):

raise ValueError(f'Invalid options {unk_args}')
ValueError: Invalid options ['256', '--wn-channels']
