Gluon NLP Horovod Issue

[gauravrele87]

I was trying to use the bert model give here using SageMaker MXNet estimator and horovod and its giving me errors

script: https://github.com/dmlc/gluon-nlp/tree/v0.10.x/scripts/bert . I was using finetune_squad.py using the following code:

from sagemaker.mxnet import MXNet
import sagemaker

sagemaker_session = sagemaker.Session()

bucket = sagemaker_session.default_bucket()

role = sagemaker.get_execution_role()

hyperparameters = {
    'comm_backend':'horovod',
    }

num_instances = 2 # How many nodes you want to use.
instance_family = 'ml.p3.2xlarge' # Which instance type you want to use.
source_name = 'finetune_squad.py'

distributions = {'mpi': {
                    'enabled': True,
                    'processes_per_host': 2, #Each instance has 8 gpus
            'custom_mpi_options': '-verbose --NCCL_DEBUG=INFO'
                        }
                }

estimator = MXNet(
                entry_point=source_name,         #Script entry point.
                source_dir='.',                #Script Location
                role=role, 
                train_instance_type=instance_family,
                train_instance_count=num_instances,
                framework_version='1.7.0',            #MXNet version.
                train_volume_size=10,                #Size for the dataset.
                py_version='py3',                     #Python version.
                hyperparameters=hyperparameters,
                distributions=distributions           #For use with Horovod.
