@MaskRay I was able to reproduce this problem in the Mac environment and printed the nodesForDataCompression information before and after the BalancePartition algorithm. I found that the input before the algorithm was consistent, but there was a difference in order after running. Is this something in the BP algorithm? some randomness or something..
@ellishg Hi ellis, do you have any idea? thx.
