如何查看下载到本地的大模型的具体大小？占了多少存储空间：Llama-3.1-8B下载到本地大概15GB

这里介绍一下tree命令，可以方便的查看文件目录结构和文件大小。
命令行tree的具体使用，请参考笔者的另一篇博客：深入了解 Linux tree 命令及其常用选项：Linux如何显示目录结构和文件大小，一言以蔽之，sudo apt-get install tree 安装之后就是tree -h命令即可显示。

下面是展示下载到本地的Llama-3.1-8B模型的具体存储空间占用：

首先说一下这里的 model-00001-of-00004.safetensors等是软连接，指向blobs中真正的模型。所以直接在blobs中查看模型大小即可。

这里总共是： 4.7G+4.6G+1.1G+4.6G = 15G,当然其他的json文件很小，我没计算。这就是Llama-3.1-8B下载到本地的具体大小。
