我收到“基于过滤器的功能选择"的错误0023 [英] I am getting an Error 0023 with a 'Filter based feature selection'

问题描述

我将包含2列，产品组和文本的数据集加载到Machine Learning Studio中.创建的模型尝试根据输入的文本分配产品组.我使用了基于过滤器的功能选择.部署并测试了Web服务之后，我得到了 下面的错误消息.我在产品组上进行了基于过滤器的功能选择.

I loaded a data set with 2 columns, product group and text into Machine Learning Studio. The model created tries to assign a product group based on an entered text. I used Filter based feature selection. After deploying and testing the web service I get the error message below. I did the filter based feature selection on product group.

该模型的确创建并给了我不错的准确性，我可以看到它在训练实验中所做的测试.设置输入参数时，我无法弄清楚我该怎么做.它甚至不应该问我产品组，因为这应该是 输出.

The model did create and gave me a decent accuracy and I can see the tests it did in the training experiment. I can't figure out what I do wrong when setting up the input parameters. It should not even ask me for product group since this is supposed to be the output.

这是错误消息:

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".

Error Message: Filter Based Feature Selection : Error 0023: Input dataset has unsupported target column "PRODUCT_GROUP".

我查看了图库中的一项实验，它有类似的错误消息

I looked at one of the experiments in the gallery and it has a similar error message

它还显示错误0023

It also shows an Error 0023

23:错误0023:输入数据集的目标列"Case_CaseType"不受支持，错误代码:ModuleExecutionError

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

这可能是我缺少的小东西，这是我的第一个模型.感谢您的所有帮助

It is probably something small I am missing and this is my first model. Thanks for all your help

推荐答案

论坛中的其他用户可能可以添加他们的建议.

Other users in the forum might be able to add in their suggestions.

基于错误描述，

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.
