--job-dir error

[jocelynbaduria]

Hi
When I tried training in cloud using this link https://github.com/GoogleCloudPlatform/tensorflow-without-a-phd/tree/master/tensorflow-mnist-tutorial/mlengine

I got error Error when submitting the job (gcloud.ml-engine.jobs.submit.training) argument --job-dir: Must be of form gs://bucket/object

I specified the bucket storage here but still got an error.
gcloud ml-engine jobs submit training jobXXX --job-dir gs:///jobs/jobXXX --project --config config.yaml --module-name trainer.task --package-path trainer --runtime-version 1.4

Kindly help..thanks
