I want to teach the m4t v2 model, but I am facing various errors
Has anyone done this?
Is this possible now?
Can you guide me?

Is there a sample code for training and fine-tuning m4t v2?
Because UnitYNART2UModel should be trained
In this case, I face errors such as RuntimeError: mat1 and mat2 shapes cannot be multiplied.
There is no problem with training the version 1 and fine tuning is done and the interesting thing is that after training on the customized data, there is no change in the output of the model and it reads as before.
I am really tired and confused after 3 months of trying

Has anyone taught the v2 model?? And is this possible now? Please explain if you remember
