1、测试环境

1.1、显卡

1.2、模型

Qwen2.5-32B-Instruct

1.3、部署环境

xinference

1.3.1、docker

docker run  \
-v ~/.xinference:/root/.xinference \
-v ~/.cache/huggingface:/root/.cache/huggingface \
-v ~/.cache/modelscope:/root/.cache/modelscope \
-e XINFERENCE_MODEL_SRC=modelscope \
-p 9998:9997 \
--gpus all \
--shm-size 20g \
--name xinference \
registry.cn-hangzhou.aliyuncs.com/xprobe_xinference/xinference:latest \xinference-local \
-H 0.0.0.0 \
--log-level debug

1.3.2、执行命令

xinference launch --model_path ~/.cache/modelscope/hub/qwen/Qwen2___5-32B-Instruct --model-engine vLLM --model-name qwen2.5-instruct --size-in-billions 32 --model-format pytorch --quantization none --n-gpu 4  --gpu-idx 0,1,2,3

2、测试问题

以下是三个需要模型“深度思考”的问题（用ChatGTP得到）：

2.1、20字左右问题

宇宙中是否存在多重宇宙，如果存在，它们之间如何相互影响？

2.2、50字左右问题

人工智能是否可能真正理解“情感”的含义？如果可以，情感的理解会如何影响人类与 AI 的关系？

2.3、100字左右问题

在人类社会的未来发展中，科技不断进步是否会导致人类完全依赖技术？如果技术突然崩溃，人类是否具备足够的韧性重新建立自给自足的社会？如何在高速发展的同时保留这种生存能力？

3、测试代码
