Sagemaker frozen after printing "Checkpoint> Saving in path=['./checkpoint/agent/0_Step-0.ckpt']" #53

Hi there. I'm running on Ubuntu 18.04 with an Nvidia Tesla P4 gpu. I've managed to get the containers running for dr-start-training with default configs and local mode. However the log froze after printing this message:

Checkpoint> Saving in path=['./checkpoint/agent/0_Step-0.ckpt']

I checked the checkpoint path and all the files were not changed at all (neither size nor modified time), while the cpu remains at 100% consumption by the python process.

I've located the source of this log message to line 61 of training_worker.py

# save initial checkpoint                                           
graph_manager.save_checkpoint()

but couldn't debug further from there.

Any idea what could be causing this problem?

Thanks
