Autogluon simple program failing with distributed training

#1

As described in doc, i used same example for distributed training with autogluon still its failing with below errors. can you help out ?

code:
@ag.args(
batch_size=64,
lr=ag.Real(1e-4, 1e-1, log=True),
momentum=0.9,
wd=ag.Real(1e-4, 5e-4),
)
def train_fn(args, reporter):
print(‘task_id: {}, lr: {}’.format(args.task_id, args.lr))
for e in range(10):
top1_accuracy = 1 - np.power(1.8, -np.random.uniform(e, 2*e))
reporter(epoch=e, accuracy=top1_accuracy)

extra_node_ips = [‘x.x.x.y’,‘x.x.x.z’,‘x.x.x.x’,‘x.x.x.v’]

scheduler = ag.scheduler.FIFOScheduler(
train_fn,
resource={‘num_cpus’: 2, ‘num_gpus’: 0},
num_trials=20,
reward_attr=‘accuracy’,
time_attr=‘epoch’,
dist_ip_addrs=extra_node_ips)
print(scheduler)

This should be fixed in PR https://github.com/awslabs/autogluon/pull/248

Could you try the master branch and let me know how it goes?

Sure will try and let you know

Thanks for the info. We’ll look at it.

Hi, looks like the TCP ports are not enabled across machines. Could you check the settings?

#8

ports are enabled and none of the open ports are blocked by default in our environment.
let me know if you want me to execute anything and reconfirm ?
