Mac平台M1PRO芯片MiniCPM-V-2.6网页部署跑通

2.6的小钢炮可以输入视频了,我必须拉到本地跑跑。主要解决2.6版本默认绑定flash_atten问题,pip install flash_attn也无法安装,因为强制依赖cuda。主要解决的就是这个问题,还有 BFloat16 is not supported on MPS问题解决。

#拉下这个仓库
git clone [https://github.com/OpenBMB/MiniCPM-V.git](https://github.com/OpenBMB/MiniCPM-V.git) 
#把requirements.txt安装下
#modelscope需要手动安装
pip install http://thunlp.oss-cn-qingdao.aliyuncs.com/multi_modal/never_delete/modelscope_studio-0.4.0.9-py3-none-any.whl
#dcord如果安装有问题,参考我LAVIS博客
#找到根目录web_demo_2.6.py运行
#首先添加环境变量,mps参数,见下图
--device mps
PYTORCH_ENABLE_MPS_FALLBACK=1
#第一次运行web_demo_2.6.py报错如下
ImportError: This modeling file requires the following packages that were not found in your environment: flash_attn. Run `pip install flash_attn`

  • 解决flash_attn强制依赖问题
  • 解决bfloat16在mps无法使用问题
  • 看系统占用是没走mps,添加的环境变量也可以看出
  • Sampling瞎回答,Beam Search回答很惊喜
  • Beam Search处理视频4秒,在m1pro下,当前代码中需要230s左右
  • ollama部署还在研究中…
MiniCPM-V是一种高效的多模态大型语言模型,可在移动设备上部署。在 OpenCompass 集合上,MiniCPM-Llama3-V 2.5 在涵盖 11 个流行基准的综合评估中,其性能优于 GPT-4V-1106、Gemini Pro 和 Claude 3。基于从AI/人类反馈中调整多语言大型模型(MLLM)行为的RLAIF-V[112]和RLHF-V[111]技术,MiniCPM-Llama3-V 2.5 展现了更可信的行为,在Object HalBench上的幻觉率低于GPT-4V-1106
