Question towards the Pre-trained weight for the Neural Machine Translation under supNMT

[MichaelCaohn]

Thank you so much for the great work and for making it public.

I have read the readme instructions for Neural Machine Translation under supNMT.

I am wondering for this En-Zh pretrained model weight, is it the weight just for En-Zh translation task, or it's a more general weight, which can be used for other translation tasks by further fine-tuning on tasks like En-Fr?
