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).

我想试用 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"

正是代码文档中的建议.

exactly how it is advised in the code documentation.

但是，我收到以下错误:

However, I am getting the 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: too few arguments

我试过调试，但我在 argparse 包方法中迷失了方向.

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

非常感谢任何帮助.

推荐答案

根据你应该使用的错误信息

According to the error message you should be using

$ python prediction.py mymodelid/mybucket myidentifier

它需要 2 个字符串，没有标志.

It expects 2 strings, without flags.

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

您还可以包含诸如--auth_host_hame=Joe"之类的值，但这是在 [] 中，因此是可选的.用法行中没有[--id ID]"术语.

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.
