当我尝试运行cts.train（）函数时，MarkLogic不断崩溃

当我尝试运行cts.train()函数时，MarkLogic一直崩溃。是我的代码还是别的？你能帮我弄清楚有什么不对吗？当我尝试运行cts.train（）函数时，MarkLogic不断崩溃

MarkLogic服务器8.0-6.4

var labels = [] 

    var voi = cts.collectionQuery(["VehicleOfInterest"]) 
    for(var v in voi) 
     labels.push({classes:{name:"car"}}) 

    v = cts.search(voi) 

    var all = [].concat.apply([], [v.toArray()]) 
    var classifier = cts.train(all, labels, {classifierType: "supports", kernel:"simple", epsilon: 0.01});

你是如何运行你的代码？这是完整的代码吗？记住v.toArray（）可以产生一个包含完整文档的大型数组; “VehicleOfInterest”集合有多大？你为什么迭代'voi'来将项目推入'labels'？ – grtjn

我正在迭代voi以将trainset的编号与标签 – Meku

相匹配，但是您正在迭代collectionQuery对象，而不是其搜索结果。 – grtjn

对象仅仅在错误的格式，我改变它是这样的，现在工作正常

labels.push({ "name": "voi doc", 
       "classes": [ 
        { 
         "name": 'car', 
         "val": 1 
        } 
       ] 
      })
