How to modify the vision encoder of llava-llama3-8b?
I'd like to replace the vision encoder of vit (openai/clip-vit-large-patch14-336) with swin-transformers v2(microsoft/swinv2-base-patch4-window8-256) I modify the code in config file. I replace 'from transformers import CLIPImageProcessor, CLIPVisionModel' with 'from transformers import (AutoImageProcessor, Swinv2Model)'. This is the whole config file.
`from mmengine.dataset import DefaultSampler from mmengine.hooks import (CheckpointHook, DistSamplerSeedHook, IterTimerHook, LoggerHook, ParamSchedulerHook) from mmengine.optim import AmpOptimWrapper, CosineAnnealingLR, LinearLR from torch.optim import AdamW from transformers import (AutoModelForCausalLM, AutoTokenizer, AutoImageProcessor, Swinv2Model)

Defaults to use random seed and disable deterministic

set log processor

but I get the error
do you know how to solve it? thank for your help
