A Cython wrapper to the IPOPT optimization package

Previous to 10.4 there was only @executablepath which pointed to the location of the executable binary (as opposed to any dylibs that it loaded). @loaderpath was introduced in 10.4 which allowed dylibs to load dependencies based on their location (and not on the location of the executable - who knows what's using the library).

The Houdini Object Model (HOM) is an application programming interface (API) that lets you get information from and control Houdini using the Python scripting language.HOM replaces the functionality of Houdini’s previous command language, HScript. In Python, the hou package is the top of a hierarchy of modules, functions, and classes that define the HOM.

Project description

This repository was forked from https://bitbucket.org/amitibo/cyipopt and isnow considered the primary repository. The fork includes a SciPy-styleinterface, ability to handle exceptions in the callback functions, and dockercontainer for easy usage.

README for cyipopt

Ipopt (Interior Point OPTimizer, pronounced eye-pea-opt) is a software packagefor large-scale nonlinear optimization. Ipopt is available from the COIN-ORinitiative, under the Eclipse Public License (EPL).

cyipopt is a Python wrapper around Ipopt. It enables using Ipopt from thecomfort of the Python programming language.

Usage

For simple cases where you do not need the full power of sparse and structuredJacobians etc, cyipopt provides the function minimize_ipopt which hasthe same behaviour as scipy.optimize.minimize, for example:

Installation

The Anaconda Python Distribution isone of the easiest ways to install Python and associated packages for Linux,Mac, and Windows. Once Anaconda (or miniconda) is installed, you can installcyipopt on Linux and Mac from the Conda Forge channel with:

The above command will install binary versions of all the necessarydependencies and cyipopt. Note that there currently are no Windows binaries.You will have to install from source from Windows or if you want a customizedinstallation, e.g. with MKL, HSL, etc.

To begin installing from source you will need to install the followingdependencies:

• C/C++ compiler
• pkg-config [only for Linux and Mac]
• Ipopt
• Python 2.7 or 3.4+
• setuptools
• cython
• numpy
• six
• future
• scipy [optiional]

The binaries and header files of the Ipopt package can be obtained fromhttp://www.coin-or.org/download/binary/Ipopt/. These include a version compiledagainst the MKL library. Or you can build Ipopt from source. The remainingdependencies can be installed with conda or other package managers.

Download the source files of cyipopt and update setup.py to point to theheader files and binaries of the Ipopt package, if LD_LIBRARY_PATH andpkg_config are not setup to find ipopt on their own.

Then, execute:

Export Ld Library Path

Docker container

Set Ld Library Path

The subdirectory docker contains a docker container with preinstalled ipoptand cyipopt. To build the container, cd into the docker directory and runmake. Then you can start the container by:

and either call ipopt directly or start a ipython shell and import ipopt.

Vagrant environment

The subdirectory vagrant contains a Vagrantfile that installs ipopt andcyipopt in OS provision. To build the environment, cd into the vagrantdirectory and run vagrant up (Requires that you have Vagrant+VirtualBoxinstalled). Then you can access the system by:

and either call ipopt directly or start a python shell and importipopt. Also, if you get source files<http://www.coin-or.org/download/binary/Ipopt/> of coinhsl and put it in thevagrant directory, the vagrant provision will detect and add them in theipopt compiling process, and then you will have ma57, ma27, and other solversavailable on ipopt binary (ma97 and mc68 were removed to avoid compilationerrors).

Reading the docs

After installing:

Then, direct your browser to build/html/index.html.

Testing

Access user level library folder mac os. You can test the installation by running the examples under the folder test.

Conditions of use

cyipopt is open-source code released under the EPL license.
