node-red-contrib-machine-learning 错误

Error in node-red-contrib-machine-learning

我正在尝试使用此库在 node-red 中实现最基本的机器学习流程:https://flows.nodered.org/node/node-red-contrib-machine-learning

This flow loads a CSV file, shuffles it and creates a training and a test partition.

我安装了:

我从 Anaconda 打开了 node-red

问题:

单击 "Start" 节点时,出现以下错误:

  1. 目前,他们的存储库中有一个已报告但未解决的错误。 错误 - 红色节点找不到您在节点中提供路径的任何文件。 解决方案(适用于 Linux 发行版和 MacOS): 提供文件的完整路径(就像我们在这个项目中所做的那样)。 我们无法在 Windows 中运行它。

  2. decision tree classifier predictor节点接受数据数组中的数组和returns预测。看看我们如何从 message to array for prediction 节点向他发送数据。每个子数组对应于应该发送以获得预测的数据:

    return {
            payload: [[...msg.payload.user_code,msg.payload.datetime]]
    };
