Base for ContentVec model

[Lukysoon]

Hello, could you please share what model is used for creating of ContentVec_500 model ? I assume, that this pretrained Contentvec_500 model is not pretrained from scratch, but finetuned.

I'm able to use ContentVec_500 in RVC, but if I train my own model with ContentVec and for base I use Contentvec_500 or hubert base from faireq repo. It doesn't work.

Thank you for info :-) I'm newbie in this area.
