NoSuchKey: The specified key does not exist.

I’ve been running through the Training an Object Detection Model tutorial and ran into an issue where training fails. The logs for the failed jobs show this error: UnhandledPromiseRejectionWarning: NoSuchKey: The specified key does not exist.

I noticed there’s a similar issue in the ibm-cos-sdk-js repo. The resolution for that issue was to use regional instead of cross-regional buckets.

Unfortunately I’ve tried using both Cross Region us-geo and Regional us-south buckets to no avail.

Here’s my current configuration:

• Machine Learning Instance in the Dallas location (https://us-south.ml.cloud.ibm.com)
• Multiple buckets tried on both us-geo and us-south

config.yaml file:

buckets:
  training: firearm-detection-storage-bucket
trainingParams:
  gpu: k80
  steps: '500'
name: firearm-detection

I’ve tried running the cli on Windows 10 with Node 10.16.3 and Ubuntu 19.04 with Node 10.13.0.

Any idea what could be causing this issue?

No problem, I just pushed cacli 1.1.9, it should at least submit the training job. There may be other training errors (still waiting for tests to finish)

So far it’s looking good! I was able to train and download a model using 1.1.9.
