python - Google Prediction API, Hello Prediction: error - Too few arguments -

today first day trying out google prediction api on anaconda python (ubuntu linux).

i wanted try out hello prediction starter code prediction.py using following:

    $ python prediction.py --object_name="mymodelid/mybucket" --id="myidentifier" 

exactly how advised in code documentation.

however, getting following error:

    usage: pred.py [-h] [--auth_host_name auth_host_name]                    [--noauth_local_webserver]                    [--auth_host_port [auth_host_port [auth_host_port ...]]]                    [--logging_level {debug,info,warning,error,critical}]                    object_name id     pred.py: error: few arguments 

i've tried debugging, lost within argparse package methods.

any appreciated.

edit: prerequisites reproduction of code include uploading data google storage. steps can found here.

according error message should using

$ python prediction.py mymodelid/mybucket myidentifier 

it expects 2 strings, without flags.

usage: pred.py [-h] [--auth_host_name auth_host_name]                ...                object_name id 

you can include values '--auth_host_hame=joe', that's in [], optional. there isn't '[--id id]' term in usage line.
