I'm sorry, but I have not the faintest idea of what you are talking about. You are going to have to explain what you are trying to do in rather more detail.

I have music which includes vocals and instruments. at the same time, I have Acappella which is vocals only. I tried to select this Acappella as noise reduction learning model but it didn't remove the vocals from the music.

That can't possibly work. Noise reduction is a statistical process based on a FFT, and you can't feed that with discrete, altering frequencies. Noise by definition is something you don't want that isn't part of the original signal. Your acapella track simply doesn't qualify, I'm afraid.

 

The only way you could do this would involve lining up the two tracks (and that vocal has to be sample-accurate to the mixed track), and inverting the acapella track against the mixed track - as an inverted mix-paste operation. And if any treatment at all has been done to the mixed track, or any reverb added, then that will remain. The alignment also has to be sample-accurate, or you stand no chance at all.

 

You would probably be better off trying to do this with the Center Channel Extractor, but the same caveats about effects and reverb still apply.
