Hi all, I have ordered a nvidia rtx 4090 GPU. It has 24GB of VRAM. Is it enough to run this model?
Yes
This is what we use as well. Runs without any issues (with flash_attention_2)
i try run this code in GPU A30 24GB it say not enough vram gpu @Corny335
from transformers import Qwen2_5_VLForConditionalGeneration, AutoTokenizer, AutoProcessor
from qwen_vl_utils import process_vision_info
# default: Load the model on the available device(s)
model = Qwen2_5_VLForConditionalGeneration.from_pretrained(
"Qwen/Qwen2.5-VL-7B-Instruct", torch_dtype="auto", device_map="auto"

# We recommend enabling flash_attention_2 for better acceleration and memory saving, especially in multi-image and video scenarios.

# default processer
processor = AutoProcessor.from_pretrained("Qwen/Qwen2.5-VL-7B-Instruct")
# The default range for the number of visual tokens per image in the model is 4-16384.
# You can set min_pixels and max_pixels according to your needs, such as a token range of 256-1280, to balance performance and cost.
# min_pixels = 256*28*28
# max_pixels = 1280*28*28
# processor = AutoProcessor.from_pretrained("Qwen/Qwen2.5-VL-7B-Instruct", min_pixels=min_pixels, max_pixels=max_pixels)

i am running it with vllm:
vllm serve "Qwen/Qwen2.5-VL-7B-Instruct" --max_model_len 8096 --limit-mm-per-prompt "image=5"
i am running it with vllm:
vllm serve "Qwen/Qwen2.5-VL-7B-Instruct" --max_model_len 8096 --limit-mm-per-prompt "image=5"
it done?
and i try to config min_pixels max_pixels, it work now
