Hi, friend. Have you resolved the problem? I need help~

I solved the problem by using the local opt_model opt-2.7b in the blip2_pretrain_opt2.7b.yaml , which come from Facebook/opt-2.7b.

In fact, I misunderstand the different usages between huggingface and the project page. The former provides a whole ckpt, while the latter need two different module ckpts (i.e., blip2_pretrained_opt2.7b.pth & opt-2.7b)
