我正在华盛顿大学的Coursera上学习机器学习课程。我在其中使用 iPython 的 graphlab。在实践中,当我执行以下命令时:

sales = graphlab.SFrame('home_data.gl/')

我收到错误消息:

InvalidProductKey                         Traceback (most recent call last)
<ipython-input-3-c5971b60b216> in <module>()
----> 1 sales=graphlab.SFrame('home_data.gl/')

/opt/conda/lib/python2.7/site-packages/graphlab/data_structures/sframe.pyc in __init__(self, data, format, _proxy)
865             self.__proxy__ = _proxy
866         else:
--> 867             self.__proxy__ = UnitySFrameProxy(glconnect.get_client())
868             _format = None
869             if (format == 'auto'):

/opt/conda/lib/python2.7/site-packages/graphlab/connect/main.pyc in get_client()

141     assert is_connected(), ENGINE_START_ERROR_MESSAGE

 ---> 92         raise e
 93     server.set_log_progress(True)
 94     # start the client

 InvalidProductKey: Product key not found.

(注意 ipython 笔记本和 home_data.gl 在同一个文件夹中。)

您需要使用命令 graphlab.product_key.set_product_key('PRODUCT KEY HERE') 为 graphlab 设置产品密钥
