Hi Vincent, Would you be comfortable sharing (redacted) details of the exact upload command you used and (redacted) extracts of the features json file that gave the upload error?
Two things I have encountered commonly myself: * uploading features to the model endpoint or model to the feature endpoint * forgotten double-quotes around the numbers in MultipleAdditiveTreesModel json Regards, Christine ----- Original Message ----- From: solr-user@lucene.apache.org To: solr-user@lucene.apache.org At: 03/06/17 13:22:40 Hi all, I've been trying to get learning to rank working on our own search index. Following the LTR-readme (https://github.com/bloomberg/lucene-solr/blob/master-ltr/solr/contrib/ltr/example/README.md) I ran the example python script to train and upload the model, but I already get an error during the uploading of the features: Bad Request (400) - Expected Map to create a new ManagedResource but received a java.util.ArrayList at org.apache.solr.rest.RestManager$RestManagerManagedResource.doPut(RestManager.java:523) at org.apache.solr.rest.ManagedResource.doPost(ManagedResource.java:355) at org.apache.solr.rest.RestManager$ManagedEndpoint.post(RestManager.java:351) at org.restlet.resource.ServerResource.doHandle(ServerResource.java:454) ... This makes sense: the json feature file is an array, and the RestManager needs a Map in doPut. Using the curl command from the cwiki (https://cwiki.apache.org/confluence/display/solr/Learning+To+Rank) yields the same error, but instead of it having "received a java.util.ArrayList" it "received a java.lang.String". I wonder how this actually is supposed to work, and what's going wrong in this case. I have tried the LTR with the default techproducts example, and that worked just fine. Does anyone have an idea of what's going wrong here? Thanks in advance! Vincent
