GBReweights seems to be not working in my case about hep_ml

Hi @Soumyatifr , interesting case. Can't guess the reason, but for sanity check - how about leaving only one variable ('HT') in training and see if it gets corrected?

Dear Alex @arogozhnikov,
Thanks for your very prompt reply, I have checked with only "HT" variable but still it doesn't want, it would be very hgelpful for me, if you can see the code [1] and the two root files , which I have uploaded to my google drive[2].

@Soumyatifr
just ran your code with single HT variable, and it clearly has strong improvements:

before reweighting

after reweighting

hopefully it looks similar in your env, otherwise there is some problem with package versions.

ok, assume that helped
