Question

当我尝试运行cts.train()函数时，MarkLogic不断崩溃。是我的代码还是其他什么？你能帮我弄清楚出了什么问题吗？

MarkLogic Server 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} );

标签中的对象格式错误，我把它改成了这样的东西，现在工作正常

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