This checking is a little tricky , is there better way ? I think you want to check whether the callback is lgb.early_stopping(5) , can we directly compare the function object with it ?

Directly comparing function object seems not working:

lightgbm.early_stopping(stopping_rounds=1) is lightgbm.early_stopping(stopping_rounds=1) # False
lightgbm.early_stopping(stopping_rounds=1) == lightgbm.early_stopping(stopping_rounds=1) # False
