result = X_train.join(y_train) result.head()AttributeError Traceback (most recent call last) <ipython-input-32-957a4f0008b1> in <module> ----> 1 result = X_train.join(y_train) 2 result.head() AttributeError: 'numpy.ndarray' object has no attribute 'join'

这个错误是因为 numpy.ndarray 对象没有 join() 方法。如果你想将 X_train 和 y_train 拼接在一起，可以使用 numpy.concatenate() 方法。例如：result = numpy.concatenate((X_train, y_train), axis=1)。然后，你可以使用 result.head() 方法查看结果的前几行。

这个错误是由于你在代码中使用了一个 numpy 数组，而这个数组没有 iloc 属性。iloc 是 pandas.DataFrame 和 pandas.Series 所具有的方法，用于选取数据集中某些行和列。你需要将 numpy 数组转换成 pandas.DataFrame 或者 pandas.Series 才能使用 iloc 方法。
