JPMML-R/r2pmml use the JPMML-XGBoost library for actual conversion work; JPMML-XGBoost does support XGBoost 0.6 for quite some time already: https://github.com/jpmml/jpmml-xgboost/commit/ec4bdc669d625dabb34fd63ae24f516d1092428c
I tried using r2pmml
What is your r2pmml version?
a more updated version of XGBoost (ver 6.0-0, which contains some important bug fixes)
The latest release of XGBoost is 0.6: https://github.com/dmlc/xgboost/releases
Where did you get this 6.0-0 from, and how does it differ from 0.6?
Does r2pmml supposed to support this updated version? If not, is there a plan to support it in the near future?
r2pmml supports XGBoost 0.4 and 0.6 releases. Haven't tested with earlier releases.
Could you attach your R XGBoost model to this issue so that I could take a look at it myself?
xgb = xgboost(...)
saveRDS(xgb, "xgb.rds")
I am sorry, I meant xgboost 0.6. I updated the r2pmml package and it seems that it fixed the error. Thanks!
Hi, I tried using r2pmml with a more updated version of XGBoost than the one found in CRAN (ver 6.0-0, which contains some important bug fixes) and got an error (see below). I used the command that worked when I used the CRAN version of XGBoost. Does r2pmml supposed to support this updated version? If not, is there a plan to support it in the near future? Thanks!
