History

This repository was forked in 2016 from https://bitbucket.org/amitibo/cyipopt and is now considered the primary repository. The fork includes a SciPy-style interface and ability to handle exceptions in the callback functions.

As of version 1.1.0 (2021-09-07), the distribution is released under the name "cyipopt" on PyPi (https://pypi.org/project/cyipopt). Before version 1.1.0, it was released under the name "ipopt" (https://pypi.org/project/ipopt).

Installation

We recommend using conda to install cyipopt on Linux, Mac, and Windows:

conda install -c conda-forge cyipopt

Other installation options are present in the documentation.

Building manylinux wheels

manylinux wheels can be built for a tagged version (GIT_TAG below) of cyipopt via docker by running (while in the root of this repo):

docker run -v $(pwd):/wheels --rm --platform=linux/amd64 quay.io/pypa/manylinux_2_28_x86_64 bash /wheels/build_manylinux_wheels.sh GIT_TAG

for linux/amd64 and:

docker run -v $(pwd):/wheels --rm --platform=linux/aarch64 quay.io/pypa/manylinux_2_28_aarch64 bash /wheels/build_manylinux_wheels.sh GIT_TAG

for linux/aarch64 platforms. Built wheels appear at the folder the command was executed from.

Warning

Docker supports emulating non-native platforms to e.g. produce ARM binaries from an AMD64 host. However this can be quite slow (~1h for our case).
