    Hi Kamal,

    To warmstart the LP you need to either provide

    It is not enough the supply VBasis values alone.

    Thanks for the clarification Riley. I tried

    for var, bas in zip(m.getVars(), I_B):
            var.VBasis = bas
    for cont, bas in zip(m.getConstrs(), I_C):
          cont.CBasis = bas

    And it worked!
