I am using xgboost4spark and I have been trying out xgboost 1.1.1.
Some of my models’ predictions fail on the following error:
Check failed: weights_.Size() == num_row_ (15363 vs. 15362) : Size of weights must equal to number of rows.
The numbers in the error are of course not always the same (but the subtraction is always 1).
The same data/model works on xgboost 0.9.
Any one know what is wrong?
