Qwen2.5-Omni: Offline inference

Source https://github.com/vllm-project/vllm-omni/tree/main/examples/offline_inference/qwen2_5_omni.

Setup

See the pipeline and deploy configuration documentation to configure memory allocation for your hardware.

Run examples

Multiple Prompts

Get into the example folder

cd examples/offline_inference/qwen2_5_omni

Then run the command below. Note: for processing large volume data, it uses py_generator mode, which will return a python generator from Omni class.

bash run_multiple_prompts.sh

Single Prompt

Get into the example folder

cd examples/offline_inference/qwen2_5_omni

Then run the command below.

bash run_single_prompt.sh

Modality control

If you want to control output modalities, e.g. only output text, you can run the command below:

python end2end.py --output-wav output_audio \
                  --query-type mixed_modalities \
                  --modalities text

Using Local Media Files

The end2end.py script supports local media files (audio, video, image) via CLI arguments:

# Use single local media files
python end2end.py --query-type use_image --image-path /path/to/image.jpg
python end2end.py --query-type use_video --video-path /path/to/video.mp4
python end2end.py --query-type use_audio --audio-path /path/to/audio.wav

# Combine multiple local media files
python end2end.py --query-type mixed_modalities \
    --video-path /path/to/video.mp4 \
    --image-path /path/to/image.jpg \
    --audio-path /path/to/audio.wav

# Use audio from video file
python end2end.py --query-type use_audio_in_video --video-path /path/to/video.mp4

If media file paths are not provided, the script will use default assets. Supported query types:

• use_image: Image input only
• use_video: Video input only
• use_audio: Audio input only
• mixed_modalities: Audio + image + video
• use_audio_in_video: Extract audio from video
• text: Text-only query
