保存的决策森林分类器失败，退出代码为255(无详细信息) [英] Saved Decision Forest Classifier Fails with Exit Code 255 (no detailed information)

问题描述

大家好

我正在使用预先训练的分类器来创建Web服务.我检查了所有计分变量都可以使用相同的名称.实验失败，并显示以下错误消息.有什么问题吗?

I am creating a webservice using a pre-trained classifier. I checked that all variables for scoring are available under the same name. The experiment fails with the below error message. What is the issue?

如果您需要其他信息，请告诉我

Let me know if you need additional information

请注意:我之前成功进行了相同的实验，但是重新训练了模型并包含了其他功能.不，它不再起作用了.

As a side note: I successfully ran the same experiment before, however retrained the model and included additional features. Not it does not work anymore.
