BrokenPipeError: [Errno 32] Broken pipe error, sweeps, dcoker container

I am using pytorch in a docker container and normal wanb logging works fine. However, sweeps are throwing me broken pipe error.

detailed output:

if opts.wandb_sweep:

wandb_config = wanb_obj.get_config()

wanb_obj.startSweep(sweep_configuration=sweep_configuration, project_name=“my-first-sweep”, function_to_run = main, count = 5)

my methods:

wandb_logging() has

wandb.init(project=“my-first-sweep”, config=self.config, dir = ‘data/logs’)


sweep_id = wandb.sweep(sweep=sweep_configuration, project=project_name)
wandb.agent(sweep_id, function=function_to_run, count=count)

Hi @kalia-megha84, thank you for reaching out. Would you mind sharing some additional information to help us troubleshoot this:

  • What version of the SDK are you running on the docker container?
  • Do you have access to the ./wandb/ folder on the container? If so, would you be able to send us the debug.log and debug-internal.log that you should be able to find in the ./wandb/run-date_time-runid/logs folder (you should have one per Run started by the sweep)
  • I see you mentioned your methods startSweep(), wandb_logging() - however, I see wandb_obj is defined as wanb_obj = wandb_logging.wandb_logging(opts). Is wandb_logging also a custom class you defined with the method wandb_logging()?
