I’m logging my experiments with W&B (wandb.ai). When I call wandb.log()
from a remote worker, it throws:
ray.exceptions.RayTaskError: ray::mapper() (pid=9299, ip=172.31.2.150)
File "python/ray/_raylet.pyx", line 480, in ray._raylet.execute_task
File "/home/ubuntu/main.py", line 90, in mapper
wandb.log({"mapper_finished": f"M-{mapper_id}"})
File "/home/ubuntu/miniconda3/lib/python3.8/site-packages/wandb/sdk/lib/preinit.py", line 38, in preinit_wrapper
raise wandb.Error("You must call wandb.init() before {}()".format(name))
wandb.errors.error.Error: You must call wandb.init() before wandb.log()
I’m not using Tune at the moment, but I see there is integration available (ray.tune.integration.wandb — Ray v2.0.0.dev0). I wonder if it would allow me to log from remote workers, then?
