exo是一个多机协同AI大模型集群软件，它可以将多种设备统一成一个强大的GPU，支持多种模型，并具有动态模型分区、自动设备发现等功能。

实践：多机协同AI大模型集群软件exo：体验github日榜第一名的魅力！-CSDN博客
在安装了exo后，一直运行没有成功，在网页运行的时候，报错让使用debug>2去调试
原来可以命令行调试运行：DEBUG=9 exo run llama-3.2-1b --disable-tui --prompt "hello"
总结
先上结论，这个模型可以：llama-3.2-1b
调试可以加上跟踪信息，比如DEBUG=9
调试
mac exo网页端交互，chat输入信息后，报错：
Failed to fetch completions: Error processing prompt (see logs with DEBUG>=2): Invalid Metal library. b''

Error: Failed to fetch completions: Error processing prompt (see logs with DEBUG>=2): Invalid Metal library. b'' at Proxy.openaiChatCompletion (http://192.168.0.108:52415/index.js:416:17) at async Proxy.processMessage (http://192.168.0.108:52415/index.js:320:19)
网页调试不便，使用命令手工运行模型：
debug=9 exo run llama-3.2-1b --disable-tui --prompt "hello"
报错信息：AssertionError: Invalid Metal library. b''
AI说可能是源代码问题，编译器问题，环境问题，tinygrad库问题。
也可能是mac太老的缘故吧，只有8g内存，估计跑不起来。deepseek还是厉害啊，8G也能跑。
先放弃mac下。
后面都是在Ubuntu下调试
报错Unsupported model 'deepseek-r1-distill-qwen-1.5b' for inference engine TinygradDynamicShardInferenceEngine
命令：DEBUG=9 exo run deepseek-r1-distill-qwen-1.5b --disable-tui --prompt "What is the mean
ing of exo?"
Error: Unsupported model 'deepseek-r1-distill-qwen-1.5b' for inference engine TinygradDynamicShardInferenceEngine
Task was destroyed but it is pending!
说Tinygrad不支持deepseek啊！
DEBUG=9 exo run deepseek-r1-distill-qwen-1.5b --disable-tui --prompt "What is the mean
ing of exo?"
换了一个模型llama-3.2-1b，这个模型报错不一样：File not found
DEBUG=9 exo run llama-3.2-1b --disable-tui --prompt "What is the meaning of exo?"
报错：FileNotFoundError: File not found: https://hf-mirror.com/unsloth/Llama-3.2-1B-Instruct/resolve/main/model.safetensors.index.json
Downloading shard.model_id='llama-3.2-1b' with allow_patterns=['*']
这个模型是可以的：
llama-3.2-3b
但是下载太耗时
使用llama-3.2-1b测试，发现报错：Error processing prompt: [Errno 2] No such file or directory: 'clang'
no clang
安装
pip install clang还是报这个clang错误
证明pip安装clang不行啊

报错信息提示没有装clang，确认一下；
clang --version
真的米有啊，一直以为安装了clang了呢。用apt安装：
sudo apt install clang现在看看版本:
clang --version
Ubuntu clang version 14.0.0-1ubuntu1.1
Target: x86_64-pc-linux-gnu
Thread model: posix
InstalledDir: /usr/bin
clang问题解决

没事，就是超时罢了，设备配置低的问题，换个简单的问题测试：

HelloHello! How can I assist you today?<|eot_id|>
它回答了，真棒！第一次运行成功！
怀念deepseek啊，比llama快多了啊。下一阶段目标，跑起来deepseek!
