WebAug 25, 2016 · I am solving my convex optimization problem with cvxpy via calling gurobi solver. However, I come across the following exception. I do not name the variable as "y". Does anyone know where results_dict["y"] comes from? Or, how to fix it? In addition, I also received a warning about the failure of inaccurate barrier solution. WebThat trouble stemmed partly from a configuration error in CVXPY’s pyproject.toml, which has been fixed in CVXPY 1.1.19 and 1.2.0. If you have those versions (or newer) then the above commands should work provided (1) you have cmake installed via Homebrew and (2) you have an ECOS 2.0.5 wheel.
