Delay loading of models?

I only have a 16gb gpu and loading all the models right away OOMs, annoying since all my audios are stemmed and dereverbed already

Thanks for the suggestion. We will optimize lazy loading for unused models in a future update. And could you confirm whether you are using the latest code? Our tests show it runs stably with 10GB VRAM.
