WebCVXOPT is a free software package for convex optimization based on the Python programming language. It can be used with the interactive Python interpreter, on the command line by executing Python scripts, or integrated in other software via Python extension modules. 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 . otherwise, run pip install . Apple M1 users ¶
