你可以dftest_raw.head()看看你的数据里有没有Survived字段，或者直接用作者提供的数据。

谢谢你的回复 @sevenold 我看了一下 的确作者提供的数据和titanic的原始数据不一样 ，可能是作者预处理过了。我按照作者源代码中的路径去下载csv文件，问题得到解决。

但是作者这么做的原因是为什么呢？ 我可以理解为作者做了一个打乱数据的行为， 而且把原始数据中的train data分割成了两部分， 一部分是train data， 一部分是test data（cross validation data）吗？ 谢谢！

是把原始数据的训练集拆分成两部分的，目的是为了构造有标签的验证集。
