首先根据官方示例教程，学会怎么创建项目，怎么使用数据，怎么进入开发环境，以及了解最重要的2个环境变量：
这个是进入开发环境以后的代码目录
$GEMINI_CODE
这个是引用数据集后，数据集存放的路径
$GEMINI_DATA_IN1
这2个linux shell环境变量很关键
创建项目时，需要注意的：
镜像选择：
数据集选择：
数据集选择后，页面会提示，数据集绑定在/gemini/data-1路径了。这个不用记忆，这个路径会保存在前面说的那个系统环境变量里，主要记住是data-#几。
运行规格选择：
这个模型你要想跑的效果快一些，必然是GPU显存多用一些，才能快，虽然6G也能跑，但是会很慢。所以选那个算力高一些的：
我第一次选的B1中等主机，结果加载到62%,直接被自动Kill了，需要大一些，建议搞large的！
上传代码：
把这三个代码上传上去,文件名别改，除非你自己懂。

然后到网页终端执行后续命令，就可以把模型跑起来
#到项目容器的代码路径
cd $GEMINI_CODE
#检查一下数据(模型)路径是不是正确绑定了，应该要能看到文件
ls $GEMINI_DATA_IN1
#更改pip源到国内镜像，清华的镜像
pip config set global.index-url https://pypi.tuna.tsinghua.edu.cn/simple
#升级一下pip到最新版
python3 -m pip install --upgrade pip
#安装 requirements.txt里模型启动需要依赖的东东
pip install --upgrade -r requirements.txt
#运行模型，这里注意几个参数，
#fp16是指GPU要在12G显存以上的显卡环境，内存要在24G左右
#8G以下显存GPU，把fp16 改为 int4
#8G显存GPU，把fp16 改为 int8
#具体在 options.py 中有说明
python webui.py --precision fp16 --model-path "$GEMINI_DATA_IN1" --listen
运行后窗口出现这类信息
就是运行成功了，访问17860端口就可以。
因为在云平台，所以还要到开发环境去再看一下，外网访问的端口，如下图 端口号17860 的位置所示
根据地址直接访问，就可以会话了。注意滚动条往下拉一下，可以找到会话窗口。
尝试完成之后，记得关闭实验环境，不然会费算力点
勾选上保存环境镜像，下次进来的时候，操作不会丢可以继续！
