Thanks @jiamingy.
Actually we are using xgboost for training and inferencing .
And we are using different versions of xgboost for different models . like xgboost [ 1.7.0 , 1.7.1, 1.7.2, 1.7.3 , 1.5.2,1.4.2 ].
But now we want to use one version of xgboost instead of different versions of xgboost for different models .
so here my question is could you pls help us to choose one version of xgboost among different versions of xgboost ?
I mean wanted to know , what is the best approach we should follow to test different versions of xgboost and pick the best among all,
for our all the models .

Hi @jiamingy
One more question
Is different versions of xgboost affect training time and inferencing time of the model ?
If answer is yes ,
Then wanted to now how it is affecting inferencing and training time for use of different versions of xgboost ,
could you pls share some link , or documents regarding this .

Yes.
