Installation¶

Requirements¶

The supported Python versions are:

• Python 3.7

• Python 3.8

• Python 3.9

• Python 3.10

• Python 3.11

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#egg=foxes

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.

Installation via conda¶

Preparation¶

It is strongly 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

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

Developers¶

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

Concerning the git clone line, we actually recommend that you fork foxes on GitHub and then replace that command by cloning your fork instead.
