[Usage]: how can i perfrome multiimage inference? in MiniCPM-V-2_6 model or any vision language model with vllm? #8215

`from PIL import Image

print(outputs[0].outputs[0].text)`

I have already givem the way i like to use vllm in my script

The text was updated successfully, but these errors were encountered:

Please check out this example which I've added just yesterday. Of course, you'll have to change the prompt to the format required by your model when using LLM.generate.

For MiniCPM-V, you have to perform a few additional modifications as shown here. Also, the prompt format is different from Phi-3-vision so you have to edit that as well.

DarkLight1337 · 2024-09-07T03:52:43Z

Multi-image support for InternVL2 isn't added to vLLM yet. See #8201

dahwin · 2024-09-07T04:03:43Z

Oky then

Dose vllm support multi image inference for MiniCPM-V-2_6?
Can you tell me please?

Yes, please follow the example files.

You need to update your vLLM version.

dahwin · 2024-09-07T11:20:41Z

Oh oky

dahwin · 2024-09-07T11:25:24Z

But

If i use the latest version of vllm! cuda showing out of memory! I have two Nvidia t4 machines! If i use two versions before the release, i can infer a single image! Now if I use the latest version my cuda is out of memory how to solve this problem!??? Is there any parameter in the latest version that can be turned off to reduce memory usage?

DarkLight1337 · 2024-09-07T13:08:04Z

Additional memory needs to be allocated when you perform multi-image inference. Can you show the code used in the old and new versions?

The first image depicts a male mallard duck swimming on a body of water. The duck's vibrant green head and yellow bill are prominent features, and its reflection is visible on the water's surface. The second image shows a male lion sitting in a grassy savanna. The lion's mane is particularly striking, and the background consists of tall, dry grass, suggesting a natural, wild habitat.
