Google Prediction API，Hello Prediction:错误-参数太少 [英] Google Prediction API, Hello Prediction: error - Too few arguments

问题描述

今天是我在Anaconda Python(Ubuntu Linux)上试用Google Prediction API的第一天.

Today is my first day trying out Google Prediction API on Anaconda Python (Ubuntu Linux).

我想尝试Hello Prediction入门代码 prediction.py 使用以下内容:

I wanted to try out the Hello Prediction starter code prediction.py using the following:

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

确切地在代码文档中得到建议.

exactly how it is advised in the code documentation.

但是，出现以下错误:

    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: too few arguments

我尝试调试，但是在argparse包方法中迷路了.

I've tried debugging, but I get lost within the argparse package methods.

非常感谢您的帮助.

再现此代码的前提条件包括将数据上传到Google Storage.可以在此处找到步骤.

Prerequisites to reproduction of this code include uploading data to Google Storage. Steps can be found here.

推荐答案

根据您应该使用的错误消息

According to the error message you should be using

$ python prediction.py mymodelid/mybucket myidentifier

它期望2个字符串，不带标志.

It expects 2 strings, without flags.

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

您还可以包括'--auth_host_hame = Joe'之类的值，但这在[]中，因此是可选的.使用行中没有"[--id ID]"一词.

You can also include values like '--auth_host_hame=Joe', but that's in [], so is optional. There isn't an '[--id ID]' term in the usage line.
