WebPerform the following steps to install CVXPY from source: Clone the official CVXPY git repository, or a newly minted fork of the CVXPY repository. Navigate to the top-level of the cloned directory. If you want to use CVXPY with editable source code, run. pip install -e . WebCVXPY provides interfaces to many mixed-integer solvers, including open source and commercial solvers. For licensing reasons, CVXPY does not install any of the preferred solvers by default. The preferred open source mixed-integer solvers in CVXPY are GLPK_MI, CBC and SCIP.

WebApr 24, 2024 · The problem was that CVXPY is not able to handle .real and .imag function inside the constraints. So the manipulation needed was to break down the complex varibale B into two real variables then combine them after the .solve using B=BR.value+1j*BI.value. The other mistake in the question was putting the constraint as LMI>=0. felyne plush
