Hi I am trying to upload a training model generated from ranklib jar using lamdamart mart.
The model is like
{"class":"org.apache.solr.ltr.model.MultipleAdditiveTreesModel",
"name":"lambdamartmodel",
"params" : {
"trees" :[
{
"id": "1",
"weight": "0.1",
"split": {
"feature": "8",
"threshold": "7.111333",
"split": [
{
"pos": "left",
"feature": "8",
"threshold": "5.223557",
"split": [
{
"pos": "left",
"feature": "8",
"threshold": "3.2083516",
"split": [
{
"pos": "left",
"feature": "1",
"threshold": "100.0",
"split": [
{
"pos": "left",
"feature": "8",
"threshold": "2.2626402",
"split": [
{
"pos": "left",
"feature": "8",
"threshold": "2.2594802",
"split": [
{
"pos": "left",
"output": "-1.6371088"
},
{
"pos": "right",
"output": "-2.0"
}
]
},
{
"pos": "right",
"feature": "8",
"threshold": "2.4438097",
"split": [
{
"pos": "left",
"feature": "2",
"threshold": "0.05",
"split": [
{
"pos": "left",
"output": "2.0"
},
......
getting an exception as :
Exception: Status: 400 Bad Request
Response: {
"responseHeader":{
"status":400,
"QTime":43},
"error":{
"metadata":[
"error-class","org.apache.solr.common.SolrException",
"root-error-class","java.lang.RuntimeException"],
"msg":"org.apache.solr.ltr.model.ModelException: Model type does not
exist org.apache.solr.ltr.model.MultipleAdditiveTreesModel",
"code":400}}
.
I have used RankLib-2.1-patched.jar to generate the model and converted the
generated xml to json.
