Using .nemo models

[ramainen]

How to use .nemo models (for example https://ngc.nvidia.com/catalog/models/nvidia:nemo:stt_ru_quartznet15x5 )?

examples/asr.py --mic 11 --model asr/quartznet-15x5_ru/ru.nemo says "ValueError: resource 'asr/quartznet-15x5_ru/ru.nemo' has invalid extension '.nemo'"

I believe .nemo converted to bin with json somehow.

Actually I looking for pre-trained russian models, but there is no russian in --list-models list.

https://github.com/dusty-nv/jetson-voice/issues/5 You can find quartznet_golos.nemo for russian language, export nemo file to onnx if you have nemo framework installed on x86, define your russian vocabulary in json file (untar .nemo file for this, you will fine .vocab file). Exported onnx file can be converted to tensorrt engine in jetson-voice on jetson nano. You can also use onnxruntime engine if you prefer.
