Hey @i-plusplus, thanks for using LightGBM. On binary classification the init score is expected to be given for the positive class.
If I give init_score while training the model, lightgbm assumes 0 to be positive event and generate raw_score for 0.
Can you provide a small, reproducible example of that? Your example is missing the data, parameters, weights, etc.

Thanks for the response @jmoralez .
It was not the issue in lightgbm. It was a issue the way I was converting the values. Sorry about this.
