Upload trained LGBMRanker model in Elastic Search

[mjadhav1]

Hi,

Is lightgbm especially lgbmranker model currently supporting model integration with elastic search like ranklib or xgboost supports? If not, is there any other way to integrate ranker model file/pickle file in elastic search?

@mjadhav1 Sorry it took so long for someone to answer you here.

We do not maintain any integrations with Elasticsearch in this repo. I suspect that by "like ranklib or xgboost supports", you're referring to this project:

• https://elasticsearch-learning-to-rank.readthedocs.io/en/latest/training-models.html
• https://github.com/o19s/elasticsearch-learning-to-rank

Pretty cool project!

I recommend that you take this feature request over there. Mention this issue there.

My personal opinion.... having that project take on ONNX support as @robhowley suggested in o19s/elasticsearch-learning-to-rank#424 is a very promising path to adding support for LightGBM there, which would make that project more easily extensible to other model types.
