Ray：Object creation will fail if spilling is required

背景

在本地搭建了Ray的单节点服务，提交任务后，Ray报错提示空间不够

报错信息示例：

(raylet) [2023-03-24 11:06:38,311 E 821713 821740] (raylet) file_system_monitor.cc:105:

/tmp/ray/session_2023-03-24_11-03-06_248168_820779 is over 95% full,

available space: 5726846976; capacity: 1006449913856.

Object creation will fail if spilling is required.

解决方案

You can free up any crud that you might have in /tmp/. It wants to spill objects over onto disk if object store is full. You can specify in ray.init() where you want objects to be spilled to.

在ray init时指定一个新的tmp目录

ray.init(_temp_dir="一个新的目录")
例如：
/xxx/xxx/ray/tmp
