Hi, in a simple problem I am getting "Dual infeasible due to empty column 'theta.10'." Yet, when I check for this column using "linear_constraints.get_coefficients", right before solving, I can clearly see that the column has several ones.
Where might be my error?

Re: Problem with "Dual infeasible due to empty column"2013-02-05T17:58:01ZThis is the accepted answer. This is the accepted answer.That solved it, thank you Daniel.
I think the message is confusing, it would be nice if it specified that a reduction of the problem had an infeasible dual (but it is really great how fast you answered with the right approach).
