6 months ago Hi： I use the LoRA to finetune my own models, but the results drop dramatically compared with the full finetuning conterparts.Here is the result table:
finetune-type MME GQA MMBench MM-Vet POPE SQA-image TextVQA full 1285.89 59.55 53.0 22.6 86.83 58.85 48.24 lora 1070.58 51.47 28.7 82.73 50.02 39.19 and here is my lora finetune bash :
LLM_VERSION="/mnt/pfs-guan-ssai/cv/ssai_mm_pt/models/TinyLlama-1.1B-Chat-v1.0" VT_VERSION="/mnt/pfs-guan-ssai/cv/ssai_mm_pt/models/TinyLLaVA-1.5B-SigLIP" DATA_PATH=/mnt/pfs-guan-ssai/cv/yangfucai/code/internlm/data/llava_data/LLaVA-Instruct-150K/llava_v1_5_mix665k.json IMAGE_PATH=/mnt/pfs-guan-ssai/cv/yangfucai/code/internlm/data/llava_data/llava_images VT_VARIANT="${VT_VERSION#*/}" LLM_VARIANT="${LLM_VERSION#*/}" deepspeed --include localhost:7 \ tinyllava/train/train.py \ --deepspeed ./scripts/tiny_llava/zero3.json \ --model_name_or_path $LLM_VERSION \ --lora_enable True --lora_r 32 --lora_alpha 64 \ --version v1 \ --data_path $DATA_PATH \ --image_folder $IMAGE_PATH\ --vision_tower $VT_VERSION \ --tune_entire_model False \ --tune_vit_from_layer 12 \ --mm_projector_type LDPv2 \ --mm_vision_select_layer -2 \ --mm_use_im_start_end False \ --mm_use_im_patch_token False \ --image_aspect_ratio pad \ --group_by_modality_length True \ --fp16 True \ --pretrain_mm_mlp_adapter ./checkpoints/tiny-llava-base-${LLM_VARIANT}-${VT_VARIANT}-ldpv2-llm-proj-pretrain/mm_projector.bin \ --output_dir ./checkpoints/tiny-llava-base-${LLM_VARIANT}-${VT_VARIANT}-finetune-llm-ldpv2-lora \ --num_train_epochs 2 \ --per_device_train_batch_size 8 \ --per_device_eval_batch_size 4 \ --gradient_accumulation_steps 4 \ --evaluation_strategy "no" \ --save_strategy "steps" \ --save_steps 50000 \ --save_total_limit 1 \ --learning_rate 2e-5 \ --weight_decay 0. \ --warmup_ratio 0.03 \ --lr_scheduler_type "cosine" \ --logging_steps 1 \ --tf32 False \ --model_max_length 3072 \ --gradient_checkpointing True \ --dataloader_num_workers 32 \ --lazy_preprocess True \ --report_to none \ --run_name tiny-llava-base-finetune-${LLM_VARIANT}-${VT_VARIANT}I want to know where the errors occur.
And I noticed that --model_name_or_path of line 11 in scripts/tiny_llava/finetune/finetune_lora.sh is set as a finetuned model, am I right?But why would we do this now that we have got a finetuned model?
and here is my lora finetune bash :
