错误0001：找不到应用数学列 [英] Error 0001: Can't find an apply math column

问题描述

您好群组。我使用应用数学来创建一个计算列，我想将其用作数据集中的一个要素，并将该列附加到数据集中。 当我更新预测实验时，它会在转换中给出错误00001消息。 不能
找到数据集中的计算列。 我调整了所有内容，以便在需要的地方添加新列。 一切都被保存并运行。 我错过了什么？ 我想在我的模型中使用此列。

Hi.  I used apply math to create a calculated column I want to use as a feature in my dataset and appended the column to the dataset.  When I update the predictive experiment it gives me the Error 00001 message in the transformation.  Can't find the calculated column in the data set.  I adjusted everything after it to include the new column where needed.  Everything was saved and run.  What am I missing?  I want to use this column in my model.

谢谢，

推荐答案

您好，

我认为您在
Apply Transformation 。数据集应该具有完全相同的模式（列数，列数）名称，数据类型）作为首次设计转换的数据集。 

I believe you are seeing this error message when Apply Transformation runs while updating your predictive experiment. The dataset should have exactly the same schema (number of columns, column names, data types) as the dataset for which the transformation was first designed. 

从错误消息
00001 看起来新列可能仍然缺失。如果您手动操作，可能会发生这种情况键入列名或者列选择器提供了运行实验时数据集中不存在的建议列。

From the error message 00001 it looks like the new column might still be missing. This may occur if you have manually typed in a column name or if the column selector has provided a suggested column that did not exist in your dataset when you ran the experiment.
