[leoozy]

Reminder

• I have read the README and searched the existing issues.

System Info

Have installed all the requirements for Qwen2-vl

Reproduction

train_mm_proj_only:True
Hello, I want to train the vision adapter and the LLM part with lora. Do I set the train_mm_proj_only as True like this:

model

model_name_or_path: Qwen/Qwen2-VL-72B-Instruct

method

stage: sft
do_train: true
finetuning_type: lora
lora_target: all

dataset

dataset: mllm_demo,identity # video: mllm_video_demo
template: qwen2_vl
cutoff_len: 8900
max_samples: 1000
overwrite_cache: true
preprocessing_num_workers: 16

output

output_dir: saves/qwen2_vl-7b/lora/sft
logging_steps: 10
save_steps: 500
plot_loss: true
overwrite_output_dir: true

train

per_device_train_batch_size: 1
gradient_accumulation_steps: 16
learning_rate: 1.0e-4
num_train_epochs: 1.0
lr_scheduler_type: cosine
warmup_ratio: 0.05
bf16: true
ddp_timeout: 180000000
visual_inputs: true
deepspeed: examples/deepspeed/ds_z3_config.json
train_mm_proj_only:True

lora

lora_alpha: 512
lora_dropout: 0.1
lora_rank: 256

eval

val_size: 0.1
per_device_eval_batch_size: 1
eval_strategy: steps
eval_steps: 500
