Installation¶

Requirements¶

The supported Python versions are:

• Python 3.8

• Python 3.9

• Python 3.10

• Python 3.11

• Python 3.12

• Python 3.13

TLDR; Quick installation guide¶

Either install via pip:

pip install foxes

Alternatively, install via conda:

conda install foxes -c conda-forge

More details, including guidelines for developers and quicker conda installations, can be found below.

Installation via pip¶

Virtual Python environment¶

First create a new venv environment, for example called foxes and located at ~/venv/foxes (choose any other convenient name and location in your file system if you prefer), by

python3 -m venv ~/venv/foxes

Then activate the environment every time you work with foxes, by

source ~/venv/foxes/bin/activate

You can leave the environment by

deactivate

The pip installation commands below should be executed within the active foxes environment.

Standard users¶

As a standard user, you can install the latest release via pip by

pip install foxes

This commands installs the version that correspond to the main branch at github. Alternatively, you can decide to install the latest pre-release developments (non-stable) by

pip install git+https://github.com/FraunhoferIWES/foxes@dev

If you are planning to run wind farm optimizations, please install the foxes-opt package:

pip install foxes[opt]

or

pip install foxes-opt

Developers¶

For developers using pip, simply invoke the -e flag in the installation command in your local clone:

git clone https://github.com/FraunhoferIWES/foxes.git
cd foxes
pip install -e .

The last line makes sure that all your code changes are included whenever importing foxes. Concerning the git clone line, we actually recommend that you fork foxes on GitHub and then replace that command by cloning your fork instead.

If you are planning to run wind farm optimizations, please also install the foxes-opt package as described above.

Optional dependencies¶

The following optional dependencies are available:

As an example, the optional dependencies eng0 are installed by

pip install foxes[eng0]

or, for development mode, from the foxes root directory by

pip install -e .[eng0]

Note that options can also be combined, e.g.

pip install foxes[test,dev,eng0]

Installation via conda¶

Preparation (optional)¶

It is recommend to use the libmamba dependency solver instead of the default solver. Install it once by

conda install conda-libmamba-solver -n base -c conda-forge

We recommend that you set this to be your default solver, by

conda config --set solver libmamba

Virtual Python environment¶

First create a new conda environment, for example called foxes, by

conda create -n foxes -c conda-forge

Then activate the environment every time you work with foxes, by

conda activate foxes

You can leave the environment by

conda deactivate

The conda installation commands below should be executed within the active foxes environment.

Standard users¶

The foxes package is available on the channel conda-forge. You can install the latest version by

conda install foxes -c conda-forge --solver=libmamba

If you are planning to run wind farm optimizations, please install the foxes-opt package instead:

conda install foxes-opt -c conda-forge --solver=libmamba

Note that the --solver=libmamba in both above commands is optional. Note that it is not necessary if you have set the libmamba solver as your default, see above.

Developers¶

The following steps require Python >= 3.11

For developers using conda, we recommend first installing foxes as described above, then removing only the foxes package while keeping the dependencies, and then adding foxes again from a git using conda develop:

conda install foxes conda-build -c conda-forge --solver=libmamba
conda remove foxes --force
git clone https://github.com/FraunhoferIWES/foxes.git
cd foxes
conda develop .

The last line makes sure that all your code changes are included whenever importing foxes. Concerning the git clone line, we actually recommend that you fork foxes on GitHub and then replace that command by cloning your fork instead.

If you are planning to run wind farm optimizations, please install the foxes-opt package in addition:

conda install foxes-opt -c conda-forge --solver=libmamba

The --solver=libmamba is optional. Note that it is not necessary if you have set the libmamba solver as your default, see above.
