`WARNING: /workspace/srcdir/xgboost/src/learner.cc:1350: Empty dataset at worker: 0` #112

I'm seeing this warning printed over and over while evaluating an XGBoost model through MLJ (calling MLJBase.predict(...) on an XGBoostClassifier). Any hint what that could be?

This looks like the warning you get when you run a prediction on empty data, which I also find extremely annoying. This warning is called from the C lib.

I'm not above checking for empty data on the Julia side and eliding the call, though it's worth contemplating whether doing so would have unforeseen consequences.
