reading files in google cloud machine learning

Question

I tried to run tensorflow-wavenet on the google cloud ml-engine with gcloud ml-engine jobs submit training but the cloud job crashed when it was trying to read the json configuration file:

with open(args.wavenet_params, 'r') as f:
   wavenet_params = json.load(f)

arg.wavenet_params is simply a file path to a json file which I uploaded to the google cloud storage bucket. The file path looks like this: gs://BUCKET_NAME/FILE_PATH.json.

I double-checked that the file path is correct and I'm sure that this part is responsible for the crash since I commented out everything else.

The crash log file doesn't give much information about what has happened:

Module raised an exception for failing to call a subprocess Command '['python', '-m', u'gcwavenet.train', u'--data_dir', u'gs://wavenet-test-data/VCTK-Corpus-Small/', u'--logdir_root', u'gs://wavenet-test-data//gcwavenet10/logs']' returned non-zero exit status 1.

I replaced wavenet_params = json.load(f) by f.close() and I still get the same result.

Everything works when I run it locally with gcloud ml-engine local train.

I think the problem is with reading files with gcloud ml-engine in general or that I can't access the google cloud bucket from within a python file with gs://BUCKET_NAME/FILE_PATH.
