Hi Akshay, did you run solr enabling learning to rank?
./bin/solr -e techproducts -Dsolr.ltr.enabled=true if you don't pass -Dsolr.ltr.enabled=true ltr will not be available. Cheers, Diego From: solr-user@lucene.apache.org At: 07/16/18 09:00:39To: solr-user@lucene.apache.org Subject: Re: Learning to rank - Bad Request Hi, I am using apache solr 7.4.0. I am trying to use learning to rank using the python script and related data provided by the lucene. which can be found at the Github <https://github.com/apache/lucene-solr/tree/releases/lucene-solr/6.4.0/solr/contrib/ltr/example> repository of the lucene solr. I am using the standard core "techproducts" I didnt change the configuration data and thus it shows the error of bad request while uploading the model to the solr. It shows the error of empty request body :- "unknown source" please suggest me how to overcome the error. Best Regards !
