Question on multi-image input #24

Open auhowielau opened 6 months ago

auhowielau commented 6 months ago

Some models (e.g. LLaVA 1.5) cannot input multiple (>3) images limited by input length (e.g., 2048). However, Evaluation Dimension 17-24 of SeedBench 2 may require inputs of up to 8 images. How do you handle such situations? Thanks!

In our code, we concat images to handle such situations just like other models. In our experiment, llava model can output reasonable loss.

For the LLaVA 1.5 model, does the concat operation transform N input images into Nx576 visual tokens? If so, for an input of 8 frames, would there be a truncation issue, as 576x8=4608 far exceeds the input length limit of 2048? Thanks!
