Hi @alexkowa Thank you very much for removing the dplyr dependency and the change to tinytest. Is it just me, or is the build now faster 🚀 Regarding this error,...

Looks like the [issue](https://github.com/dmlc/xgboost/issues/5935) is already fixed in [XGBoost v1.3.0](https://github.com/dmlc/xgboost/releases/tag/v1.3.0 )
