下载安装googe开源大语言模型llama2

test -
  1. 点击本地址 https://ai.meta.com/resources/models-and-libraries/llama-downloads/ 填写申请表后，去邮箱查看，获取你的唯一下载链接。your unique custom URL。链接24小时内有效
  2. Visit the Llama repository in GitHub and follow the instructions in the README to run the download.sh script.

常见坑和错误：

  1. sh download.sh 出错：“download.sh: 12: [[: not found” 。应该使用bash download.sh 或者chmod +x download.sh then ./download.sh
  2. 下载 llama-2-70b-chat 时大概129G，一直开着终端，有时会待机而导致退出。建议修改download.sh 把下载链接和模型写死，然后使用  nohup 下载。我在这个问题下了3次都没成功，最后第二天又申请了下载链接。‌‌
  3. 129G分割成多个xG文件，必须一口气下完，我想下载最后一个，暂时没空研究。
