Vary Weights

Due to download speed issues with Baiduyun, we have temporarily closed the download link. Our weights will be reorganized and open source again in the next few days. If you are in urgent need of weights for your research recently, please contact me by email.
Download the CLIP-VIT-L in Hugging Face

Demo

Update the CLIP-VIT path in the codes (/cache/vit-large-patch14/) to your path.

python vary/demo/run_qwen_vary.py  --model-name  /vary/model/path/ --image-file /an/image/file.png

Train

We currently do not plan to open source the weights of the intermediate.
However, we release the train codes. So you can train on your own dataset. If you want to do this, you can try this:

For Vary-base (one machine, if you have multiple machines you need to prepare your host file)

deepspeed   Vary/train/train_qwen_vary.py  --deepspeed /Vary/zero_config/zero2.json
            --model_name_or_path /Qwen-7B/path/
            --vision_tower /vit-large-patch14/path/
            --freeze_vision_tower True
            --freeze_lm_model False
            --vision_select_layer  -2
            --use_im_start_end True
            --bf16 True
            --per_device_eval_batch_size 4
            --gradient_accumulation_steps 1
            --evaluation_strategy "no"
            --save_strategy "steps"
            --save_steps 5000
            --save_total_limit 1
            --weight_decay 0.
            --warmup_ratio 0.03
            --lr_scheduler_type "cosine"
            --logging_steps 1 --tf32 True
            --model_max_length 4096
            --gradient_checkpointing True
            --dataloader_num_workers 4
            --report_to none
            --per_device_train_batch_size 4
            --num_train_epochs 1
            --learning_rate 5e-5
            --datasets  data_name1+data_name2+data_name3
            --output_dir /path/to/output/

For Vary-tiny

deepspeed   Vary/train/train_opt.py  --deepspeed /Vary/zero_config/zero2.json
            --model_name_or_path /opt125m/path/

            --save_steps 5000
            --save_total_limit 1
            --weight_decay 0.
            --warmup_ratio 0.03
            --lr_scheduler_type "cosine"
            --logging_steps 1 --tf32 True
