Canary 1b

[janjanusek]

Hello,
is it possible to ise scripts for nemo model conversion to convert this model?

https://huggingface.co/nvidia/canary-1b

I'm asking because it supports put of the mox also translation and other tasks but I'm okay to have only it asr capabilities.

Thank you

Can you test if it works? We have not tried to do that since it is very large and if you run it on CPU, it would be very slow.

unfortunatelly no,

it crashed when I tried to convert to onnx
