# xgboost4j
|
|
this is a java wrapper for xgboost
|
|
|
|
the structure of this wrapper is almost the same as the official python wrapper.
|
|
|
|
core of this wrapper is two classes:
|
|
|
|
* DMatrix: for handling data
|
|
|
|
* Booster: for train and predict
|
|
|
|
## usage:
|
|
please refer to [xgboost4j.md](doc/xgboost4j.md) for more information.
|
|
|
|
besides, simple examples could be found in [xgboost4j-demo](xgboost4j-demo/README.md)
|
|
|
|
|
|
## build native library

|
|
|
for windows: open the xgboost.sln in windows folder, you will found the xgboostjavawrapper project, you should do the following steps to build wrapper library:
|
|
* Select x64/win32 and Release in build
|
|
* (if you have setted `JAVA_HOME` properly in windows environment variables, escape this step) right click on xgboostjavawrapper project -> choose "Properties" -> click on "C/C++" in the window -> change the "Additional Include Directories" to fit your jdk install path.
|
|
* rebuild all
|
|
* move the dll "xgboostjavawrapper.dll" to "xgboost4j/src/main/resources/lib/"(you may need to create this folder if necessary.)
|
|

|
|
* make sure you have installed jdk and `JAVA_HOME` has been setted properly
|
|
* run "create_wrap.sh"
