Installing FLORIS

The installation procedure for FLORIS varies depending on the inteded usage. Developers of FLORIS will download the source code and install it in a manner that allows running the local source code. On the other hand, those who want to run the “released” version of FLORIS in their own script can install with a package manager.

Basic Installation

To run a released version of FLORIS, you can install via pip or conda. By default, this installs that latest released version. To install a specific version, specify that as shown below.

# Using pip...
pip install floris         # Latest version
pip install floris==1.1.0  # Specified version number

# Using conda...
conda install floris        # Latest version
conda install floris=1.1.0  # Specified version number

After installation, the FLORIS package can by imported in a Python program similar to any other package.

import floris
print( help( floris ) )
print( dir( floris ) )
print( help( floris.simulation ) )

Advanced Installation

You may prefer to download the source code of FLORIS and install it on your system. This is required for developing FLORIS, but it is also useful to study the software since an extensive set of examples are provided with the repository.

The FLORIS repository consists of two primary branches:

  • master - Stable release corresponding to a specific version number.

  • develop - Latest updates including bug fixes and improvements but possibly unstable.

To download the source code, use git clone. Then, add it to your Python path with the “local editable install” through pip.

# Download the source code.
git clone

# Install into your Python environment
pip install -e floris

If everything is configured correctly, any changes made to the source code will be available directly through your local Python. Remember to re-import the FLORIS module when changes are made if you are working in an interactive environment like Jupyter.

Developer Installation

The FLORIS development team has included automatic code linting and formatting utilities that are executed at every commit. This is accomplished through the following add-ons:

There are some extra steps required to align your development environment with the FLORIS development team’s.

Clone the repository and checkout the develop branch:

git clone
cd floris
git checkout develop

Install FLORIS with the developer add-ons


You must include the two quotes () and the dot (.)!

pip install -e '.[develop]'

Install the pre-commit utility:

pre-commit install

Finally, check out For Developers for guidance on merging your updates to FLORIS with the NREL repository as well as for building the documentation locally.

Happy coding!
