ray 有自带的web管理页面吗？

Question

副标题，无法访问 ray 自带的web管理页面

ray 最近在使用这个工具

我问了 chatgpt、kimi、智谱、豆包都说有对应的 web 管理页面

告诉我可以这样用

ray start --head --port=6379 --dashboard-host 0.0.0.0 --dashboard-port 8265

但是我要访问 http://127.0.0.1:8265/ 却不行

╰─➤  http http://127.0.0.1:8265                                             
HTTP/1.1 503 Service Unavailable
Connection: close
Content-Length: 0
Proxy-Connection: close

Answer 1

问题解决了

原有是缺少依赖（很无语，缺依赖也不警告或者报错）

下面这样是不够的

pip install ray

要下面这样才行

pip install ray[default]

然后再

─➤  ray start --head --port=6379 --dashboard-host 0.0.0.0 --dashboard-port 8265
