# Qwen3-VL Evaluation Script with vLLM Backend
# This script demonstrates how to evaluate Qwen3-VL models using vLLM for accelerated inference
#
# Requirements:
# - vllm>=0.11.0
# - qwen-vl-utils
# - CUDA-enabled GPU(s)
#
# Installation:
# uv add vllm qwen-vl-utils
# OR
# pip install vllm>=0.11.0 qwen-vl-utils
