Warning : consider saving it again for improved compatibility

#1

I am running my model for last 2 years on my server. Recently I am getting this warning

WARNING: /Users/karim/Downloads/xgboost/python-package/build/temp.macosx-10.15-x86_64-3.7/xgboost/src/learner.cc:724: Loading model from XGBoost < 1.0.0, consider saving it again for improved compatibility

Why I am getting this warning? How it can be removed?

I searched on Google and github but did not get any solution for this.

Did you upgrade XGBoost? You can pin XGBoost version to 0.90 to remove warning. The reason is that XGBoost 1.x uses a different model format, so the warning is produced.
