In the GitHub documentation, it mentions following llava, so I also tried testing with llava, but the results aren't coming out well. It seems I might be doing something wrong. Could you please provide an example code?
https://github.com/SpursGoZmy/Table-LLaVA/blob/main/scripts/v1_5/table_llava_scripts/table_llava_inference.sh

# Table-LLaVA/scripts/v1_5/table_llava_scripts
/table_llava_inference.sh
for IDX in $(seq 0 $((CHUNKS-1))); do
    CUDA_VISIBLE_DEVICES=${GPULIST[$IDX]} python -m llava.eval.model_vqa \
        --model-path path_to_LLM_weights/table-llava-v1.5-7b/ \

Maybe this is because the saved Table-LLaVA checkpoints from the original LLaVA repository is not directly compatible with the Transformers, which is mentioned in this github issue. I will try the provided conversion script and upload new checkpoints. But for now, maybe the checkpoints can only be loaded locally instead of loading from HuggingFace, i.e., download Table-LLaVA checkpoints and set the 'model-path' to your local path of the model weights folder?
