Anaconda 橙色折线图小部件有问题
我正在尝试用Orange开发一个机器学习管道，我在tLine chart小部件上遇到了问题，我无法理解为什么 当我将神经网络预测与目标变量进行比较时，我可以在管道的末尾使用它，它精确地描绘了我想要它的样子 然而，当我尝试在管道的开头使用小部件时，我得到了这个错误消息Anaconda 橙色折线图小部件有问题,anaconda,orange,Anaconda,Orange,我正在尝试用Orange开发一个机器学习管道，我在tLine chart小部件上遇到了问题，我无法理解为什么 当我将神经网络预测与目标变量进行比较时，我可以在管道的末尾使用它，它精确地描绘了我想要它的样子 然而，当我尝试在管道的开头使用小部件时，我得到了这个错误消息 Error encountered in widget Line Chart: Traceback (most recent call last): File "/Users/craigmcallister/o
