基于过滤器的功能选择:错误0023:输入数据集的目标列不受支持 [英] Filter Based Feature Selection : Error 0023: Input dataset has unsupported target column

问题描述

我使用了具有两列(产品组和文本)的数据集，并创建了一个模型来根据商品的文本预测产品组.我创建了训练实验并获得了不错的成绩，然后让系统创建了预测性实验， 部署了Web服务.

I used a dataset with 2 columns (product group and text) and created a model to predict the product group based on the text for an item. I created the training experiment and got a decent score and then had the system create the predictive experiment and deployed the web service.

在测试已部署的Web服务时，它询问我产品组和文本(只应询问产品组)，然后出现以下错误:

When testing the deployed web service it is asking me for product group and text (should only ask for product group) and then gives me the following error:

错误消息:基于过滤器的功能选择:错误0023:输入数据集包含不受支持的目标列"PRODUCT_GROUP".

我还使用了具有相同步骤的画廊样本，并得到了类似的错误:

I also used a sample from the gallery with the same steps and got a similar error:

它还显示错误0023

It also shows an Error 0023

23:错误0023:输入数据集包含不受支持的目标列"Case_CaseType".，错误代码:ModuleExecutionError

23: Error 0023: Input dataset has unsupported target column "Case_CaseType"., Error code: ModuleExecutionError

您知道为什么使用错误的输入参数创建Web服务吗?

Any idea why the web service is created with the wrong input parameters?

感谢您的帮助

推荐答案

对于错误0023，e xception.

For error 0023, exception occurs if target column of input dataset is not valid for the current trainer module.

如果目标列(在模块参数中选择)不是有效的数据类型，包含所有缺失值或未按预期分类，则会发生Azure Machine Learning中的错误.

This error in Azure Machine Learning occurs if the target column (as selected in the module parameters) is not of the valid data-type, contained all missing values, or was not categorical as expected.

重新访问模块输入以检查标签/目标列的内容.确保它没有所有缺少的值.如果模块期望目标列是分类的，请确保目标列中有多个不同的值.

Revisit the module input to inspect the content of the label/target column. Make sure it does not have all missing values. If the module is expecting target column to be categorical, make sure that there are more than one distinct values in the target column.

请检查该列中是否缺少任何值，以及是否有任何类型不正确.有关更多信息，您可以参考《故障排除指南》:https://docs.microsoft.com/en-us/azure/machine-learning/studio/troubleshooting-creating-ml-workspace

Please check if you have any missing value in that column, and if there any type is not right. For more, you can refer to Trouble shooting guide: https://docs.microsoft.com/en-us/azure/machine-learning/studio/troubleshooting-creating-ml-workspace
