How to change the ray session name format?

alexlenail · February 2, 2023, 6:42pm

the docs (Configuring Ray — Ray 2.8.0) read:

Each Ray session will have a unique name. By default, the name is session_{timestamp}_{pid} . The format of timestamp is %Y-%m-%d_%H-%M-%S_%f

How can I change the session name format from ray.init()? I keep running into an error because the names are really long.

OSError: AF_UNIX path length cannot exceed 107 bytes: '/state/partition1/slurm_tmp/21322766.4294967291.0/ray/session_2023-02-02_13-15-02_941811_78876/sockets/plasma_store'

ray.init fails when temp_dir too long (but still reasonable)

### What is the problem? When I set `temp_dir` argument of `ray.init` to a pa…th that is still reasonably short (50 characters), exception about `File name too long` is thrown. See the code and traces below. ### Reproduction (REQUIRED) Script: ``` import ray ray.init(temp_dir='/tmp/aaaaaaaaaabbbbbbbbbbaaaaaaaaaabbbbbbbbbbaaaaa') ``` Trace: ``` 2020-03-24 10:24:03,788 INFO resource_spec.py:212 -- Starting Ray with 4.59 GiB memory available for workers and up to 2.3 GiB for objects.

hi @alexlenail unfortunately we don’t allow you to change the path format as of today. Let us revisit the issue in 2.4.

@Chen_Shen was it resolved so far? I am struggling with this issue and I see no fix available online.

Unfortunately, it’s not supported yet. Feel free to create a GH feature request and mention why you want that.
