Ablation study on using just single path encoder?
The model you mentioned with a single visual path is exactly LLaVA-1.5. We have conduct extensive comparisons in Tab 1 of our paper. Check out our paper.
I notcied that you enlarge the size in llava-1.5 are using interpolate positional embedding after calculate position_ids.
This would notiablly drop performance as model haven't seen large sizes when training.
What I mean is that, have u did experiment on enlarge input size by interpolate position embedding weight, and then train it along with vision encoder or full model.
How do u think the differences of these two ways.
(Your interpolate embedding seems not trainable parameters. I didn't see a resize_position_embedding before training here but just interpolate after calculated position_ids)
@luogen1996 Hello, I am doing sft stage2 follow your code, using zero3 finetune, got some warnings:
- vision_model.head.layernorm.bias: found shape torch.Size([1152]) in the checkpoint and torch.Size([0]) in the model instantiated

there was some reports: https://github.com/microsoft/DeepSpeed/issues/3574 indicates it related to enabling gradient_checkpoing and zero3 at the same time.
Does this effect model training? It looks like loss are normal
I don't see these warnings in my logs. Weights you print are not used in model, so maybe you can directly ignore them.
The model you mentioned with a single visual path is exactly LLaVA-1.5. We have conduct extensive comparisons in Tab 1 of our paper. Check out our paper.
In table 1, are llava 1.5 trained on different resolutions? or only eval in different resolutions?

@luogen1996 Thanks~

Yes, we train llava 1.5 on different resolution. The training settings are the same as llava-hr, which includes low-resolution pre-training and high-resolution instruction tuning.

Hello, I also meet this problem.. Could you please share how you resolved it?
