我有turi graphlab的设置环境，并尝试使用https://turi.com/products/create/docs/generated/graphlab.product_sentiment.ProductSentimentModel.html#graphlab.product_sentiment.ProductSentimentModel上的教程执行

这些行在jupyter笔记本中安装后运行良好

import graphlab as gl

data = gl.SFrame('https://static.turi.com/datasets/amazon_baby_products/amazon_baby.gl')

data = data.head(10000)

但是在使用建立模型时

m = gl.product_sentiment.create(data,features=['review'])

我收到以下错误消息：

---------------------------------------------------------------------------

我已经检查过http://forum.turi.com/discussion/622/，但是由于我使用的是最新的许可版本2.1，因此并没有太大帮助

任何帮助将不胜感激。
