WebApr 15, 2024 · cvxpylayers is a Python library for constructing differentiable convex optimization layers in PyTorch, JAX, and TensorFlow using CVXPY. A convex optimization layer solves a parametrized convex optimization problem in the forward pass to produce a solution. It computes the derivative of the solution with respect to the parameters in the … WebJan 15, 2024 · The XPRESS interface has been minimally maintained since migrating to cvxpy 1.0. I don't think anyone has tested changes from cvxpy's 1.0 -> 1.1 upgrade. Per a comment on #382, a community license (suitable for running unittests with cvxpy) can be installed with pip install xpress. I installed XPRESS in this way, and ran the full suite of ...
