ASR: How to convert .ckpt to nemo correctly?

[ican24]

Hi,
I am trying to convert .ckpt to nemo file correctly using following code and other recommendations, but the result poor:
asr_model = nemo_asr.models.EncDecCTCModel.load_from_checkpoint(model_ckpt) asr_model.save_to(path)
The recognized text is coming with tokenized characters
['▁some▁text']
It is impossible to use as root model for further training.
Thank you advance!
