Hi,

I am trying to add the absolute values of 16 variables. But gurobipy is throwing the following error:

TypeError: unsupported operand type(s) for +: 'GenExprAbs' and 'GenExprAbs'

How can I sum up the absolute values of variables?

  As I mentioned in my reply in the support request, the typical way to do this is to use auxiliary variables. Please see How to add a constraint which is the absolute value is smaller than a constant? for a similar question and explanation.
