Question

我正在使用python将数据导入到运行预测的服务器上我使用以下代码来设置EventClient：

import predictionio
client = predictionio.EventClient(
    access_key='285',
    url='http://localhost:7070',
    threads=5,
    qsize=500)

client.create_event(
                event="rate",
                entity_type="user",
                entity_id="Bob",
                target_entity_type="item",
                target_entity_id="Fred",
                properties= { "rating" : 5.0 }
            )

但是我不断收到以下消息：

python imp.py
Traceback (most recent call last):
  File "imp.py", line 6, in <module>
    qsize=500)
  File "C:\...\predictioni
    "It seems like you are specifying an app_id. It is deprecate
DeprecationWarning: It seems like you are specifying an app_id.
ss_key instead. Or, you may use an earlier version of this sdk.

我明确没有指定app id，因为我正在向客户端传递一个命名参数：＆＃34; access_key＆＃34;。删除qsize参数不执行任何操作，错误只会归咎于上面的行，依此类推。我无法在documentation中找到任何内容，可能是因为我对所有这些都很新，我无法找到我要去的地方错了。
我一直在研究的所有教程都以这种方式创建EventClients，它没有问题：

任何帮助将不胜感激。感谢。

access_key的长度必须大于8个字符。

源代码

class EventClient(BaseClient):

  def __init__(self, access_key,
      url="http://localhost:7070",
      threads=1, qsize=0, timeout=5, channel=None):
    assert type(access_key) is str, ("access_key must be string. "
        "Notice that app_id has been deprecated in Prediction.IO 0.8.2. "
        "Please use access_key instead.")

    super(EventClient, self).__init__(url, threads, qsize, timeout)

    # SEE HERE...

    if len(access_key) <= 8:
      raise DeprecationWarning(
          "It seems like you are specifying an app_id. It is deprecated in "
          "Prediction.IO 0.8.2. Please use access_key instead. Or, "
          "you may use an earlier version of this sdk.")

例如

>>> client = predictionio.EventClient(access_key='12345678')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/env/py2/lib/python2.7/site-packages/predictionio/__init__.py", line 178, in __init__
    "It seems like you are specifying an app_id. It is deprecated in "
DeprecationWarning: It seems like you are specifying an app_id. It is deprecated in Prediction.IO 0.8.2. Please use access_key instead. Or, you may use an earlier version of this sdk.
>>> client = predictionio.EventClient(access_key='123456789')
>>>

预测似乎误读了我的论点
