Answer 1

Check your xgboost library version. I loaded a model saved from xgboost==1.5.0 env to a xgboost==1.6.0 env and got the same error when operating on the model. I downgraded xgboost to 1.5.0 and everything worked fine. I suspect the model saving format is changing since 1.6.0 as it gives warning about me loading a binary model file using pickle dump.

Answer 2

We made:

!pip install xgboost==1.5.0

And it ran perfectly
