部署Kimi-VL-A3B-Instruct视频推理

契机

⚙ 最近国内AI公司月之暗面推出了Kimi-VL开源视觉模型。模型参数16.4B，但是推理时候激活参数2.8B。看了huggingface主页的Full comparison，在多项Benchmark的时候都展示出了不俗的实力。由于业务中使用了qwen-vl-2.5-7B，所以测试下Kimi-VL-A3B-Instruct是否在更小的部署资源中拥有更好的表现。

moonshotai/Kimi-VL-A3B-Instruct · Hugging Face

安装

conda create --name Kimi-VL python=3.11.0
conda activate Kimi-VL
git clone https://github.com/MoonshotAI/Kimi-VL.git
pip install -r requirements.txt
#额外安装视频推理所需依赖
pip install opencv-python
#flash-attn的安装会访问github，如果网络没有魔法，建议尝试其他办法
pip install -U flash-attn --use-pep517 --no-build-isolation#模型下载
moonshotai/Kimi-VL-A3B-Instruct#运行期间用以下命令查看显卡资源，按照0.5s刷新一次
nvidia-smi -l 0.5
