Was a pre-trained model used for opensora-v1-1 training?

[Darius-H]

I noticed that in report01.md it mentions “We initialize our model with PixArt-α and initialize the projection layer of inserted temporal attention with zero.” However in the report02.md there is no mention of this item. Also configs/openrosa-v1-1/stage1.py model.from_pretrained=None. Could it be that opensora-v1-1 is randomly initialized? Or is opensora-v1-1 using a pretrained model from opensora-1 ?
