I’m developing an app that uses xgboost4j on MacOS (Ventura 13.5.1) with M1 chip.
The xgboost4j version we used was 1.7.5
The app is deployed on a Linux server so we didn’t notice the problem before, but when we implemented unittests and made them run on Mac the following error arose:
java.lang.ExceptionInInitializerError at com.mygroup.UtilsTest.toDMatrix(UtilsTest.java:134) Caused by: java.lang.RuntimeException: java.io.FileNotFoundException: File /lib/macos/aarch64/libxgboost4j.dylib was not found inside JAR.
NOTE: The problem happens only with JDK >11.0.13, while using JDK 8 or JDK <= 11.0.13 it works.
Following #7501, I tried to rebuild the package on my M1 Mac.
I followed the guide here for the compilation, but when launching the tests it now says:
java.lang.NoClassDefFoundError: Could not initialize class ml.dmlc.xgboost4j.java.XGBoost
This is thrown when XGBoost.loadModel(path) is called.
NOTE: This error happens with both JDK 8 and 11
NOTE2: The following error now appears too (may be unrelated, but it doesn’t appear with maven version of xgb)
First i tried building version 1.7.5, but seeing that it lead to these errors i tried with a newer version (latest master commit, version 2.1.0-SNAPSHOT), but the problem is still the same.
I also tried
brew install libomp and commenting
CONFIG["USE_OPENMP"] = "OFF", but still no change after that.
Can anyone help me understand what the problem is here?
I’ve seen some people saying that recompiling on MacOS worked for them, so i don’t know what I’m doing wrong here.
