Join the conversation! For issues and long-form discussions, use Github Issues and Github Discussions. It allows you to express your problem in a natural way that follows the math, cvxpy, rather than in the restrictive standard form required by solvers. For example, cvxpy, the following code solves cvxpy least-squares problem where the variable is constrained by lower and upper bounds:.

Join the conversation! It lets you express your problem in a natural way that follows the math, rather than in the restrictive standard form required by solvers. In addition to convex programming, CVXPY also supports a generalization of geometric programming, mixed-integer convex programs, and quasiconvex programs. For applications to machine learning, control, finance, and more, browse the library of examples. For background on convex optimization, see the book Convex Optimization by Boyd and Vandenberghe. Additional solvers are supported, but must be installed separately.

Cvxpy example, cvxpy, the following code solves a least-squares problem where the variable is constrained by lower and upper bounds:. About A Python-embedded modeling language for convex optimization problems. A member of the CVXPY development team cvxpy review the pull request and guide you through the contributing process.

You can use pip or conda for installation. You may want to isolate your installation in a virtualenv , or a conda environment. Windows only Download the Visual Studio build tools for Python 3 instructions. Windows only Download the Visual Studio build tools for Python 3. Install conda. Install cvxpy from conda-forge. We strongly recommend using a fresh virtual environment virtualenv or conda when installing CVXPY from source.

Cvxpy

This section of the tutorial describes the atomic functions that can be applied to CVXPY expressions. This is now deprecated. Starting with Python 3. Elementwise multiplication can be applied with the multiply function. For example, if expr has shape 5, then expr[1] gives the second entry. More generally, expr[i:j:k] selects every kth element of expr , starting at i and ending at j If expr is a matrix, then expr[i:j:k] selects rows, while expr[i:j:k, r:s:t] selects both rows and columns. Indexing drops dimensions while slicing preserves dimensions.

It allows you to express your problem in a natural way that follows the math, rather than in the restrictive standard form required by solvers. To share feature requests and bug reports, use the issue tracker. Minimize cp. It is now developed by many people, across many institutions and countries. CVXPY 1. We welcome all kinds of issues, especially those related to correctness, documentation, performance, and feature requests. Initially, a second backend based on the SciPy sparse module was added. A Python-embedded modeling language for convex optimization problems. You don't need to be an expert in convex optimization to help out. Contributions should be submitted as pull requests. Problem objective , constraints The optimal objective is returned by prob. Skip to content.

It automatically transforms the problem into standard form, calls a solver, and unpacks the results.

For more information about the team and our processes, see our governance document. CVXPY is not a solver. The CVXPY community consists of researchers, data scientists, software engineers, and students from all over the world. For issues and long-form discussions, use Github Issues and Github Discussions.
