title: Google cloud-ml stuck without logs after several iterations
body: <p>I am training a TF ML job on cloud-ml, and it seems the job is stuck after a few iterations (900 iterations). Surprisingly, when I run the code locally it works fine, and also hyper tuning on GCP continues training but runs slower than my local laptop which has a 1060GTX GPU.
  I am also using the runtime version 1.6.</p>
  
  <p>I changed the scale-tier and it doesn't help. What can be the issue? </p>
