Installation

Stable

Stable releases can be installed on osx and linux using a combination of conda and pip.

conda create -n cra -c conda-forge python=3.10 pyomo=6.4.2 ipopt=3.14.9 compas compas_viewer
conda activate cra
pip install compas_assembly compas_cra

Latest

The latest version can be installed on osx and linux from local source using an environment file.

git clone https://github.com/blockresearchgroup/compas_cra.git
cd compas_cra
conda env create -f environment.yml
conda activate cra-dev

Note that this will automatically create an editable install that can be used for development.

Windows

On Windows, the first part of the installation is the same.

However, once you start using CRA, you will very likely run into a problem with missing ipopt binares. To solve this, you can download the binaries from the ipopt github release and place it in in the correct folder of you environment. (Thank you Petras for figuring this out :)

The bnary of release ipopt=3.14.9 is available here:

• <coin-or/Ipopt>

Copy the contents of the bin folder of the archive into the Library\bin of your environment. For example, into C:\Users\You\anaconda3\envs\cra\Library\bin.

If this still doesn’t fix the problem, please let us know.
