When I run housing_paper.py in Linux, I got the following error:
"Solver '%s' failed. Try another solver." % solver.name())
cvxpy.error.SolverError: Solver 'ECOS' failed. Try another solver.

I'm working on cvxpy 1.0. There will be some changes to the user interface. These fall into three categories:
1. Making cvxpy syntax more like NumPy.
- The `expr.value` and `constraint.dual_value` …

Ok, time to figure out the user-facing side of default solvers. As of https://github.com/JuliaOpt/JuMP.jl/pull/959, we have the following significant changes:
1. An informational message is printed w…

Currently to get the optimal cost (objective) of an optimization problem, I will need to loop through all costs, and evaluate each costs at the optimal solution. On the other hand, in most solvers (ac…

We have a number of methods implemented in `bullet_model.cc` which inherently assume that the meshes involved are convex:
- `BulletModel::collisionDetectFromPoints`

`SCIP` allows for user defined expressions. One could in principle give the evaluations via callbacks (as I guess other solvers do), in case we cannot understand the expression provided to MPB.
This…

I am encountering this weird behavior:
``` julia
function oo()
prog = Model(solver=IpoptSolver(print_level=0))
