Installation
The subsequently described installation steps are demonstrated as shell commands, where the path before the % sign denotes the directory in which the commands following the % should be entered.
Clone the Repository
First of all, clone the PyPSA-Eur repository using the version control system git.
System Message: WARNING/2 (<stdin>, line 20)
Cannot analyze code. Pygments package not found.
.. code:: bash
/some/other/path % cd /some/path/without/spaces
/some/path/without/spaces % git clone https://github.com/PyPSA/pypsa-eur.git
Install Python Dependencies
PyPSA-Eur relies on a set of other Python packages to function. We recommend using the package manager and environment management system conda to install them. Install miniconda, which is a mini version of Anaconda that includes only conda and its dependencies or make sure conda is already installed on your system. For instructions for your operating system follow the conda installation guide.
The python package requirements are curated in the envs/environment.yaml file. The environment can be installed and activated using
System Message: WARNING/2 (<stdin>, line 40)
Cannot analyze code. Pygments package not found.
.. code:: bash
.../pypsa-eur % conda env create -f envs/environment.yaml
.../pypsa-eur % conda activate pypsa-eur
Note that activation is local to the currently open shell! After opening a new terminal window, one needs to reissue the second command!
Note
If you have troubles with a slow conda installation, we recommend to install mamba as a fast drop-in replacement via

Cannot analyze code. Pygments package not found.
.. code:: bash
conda install -c conda-forge mamba
and then install the environment with
System Message: WARNING/2 (<stdin>, line 60)
Cannot analyze code. Pygments package not found.
.. code:: bash
mamba env create -f envs/environment.yaml
Install a Solver
PyPSA passes the PyPSA-Eur network model to an external solver for performing a total annual system cost minimization with optimal power flow. PyPSA is known to work with the free software
and the non-free, commercial software (for some of which free academic licenses are available)
For installation instructions of these solvers for your operating system, follow the links above. Commercial solvers such as Gurobi and CPLEX currently significantly outperform open-source solvers for large-scale problems. It might be the case that you can only retrieve solutions by using a commercial solver.

Note
The rules :mod:`cluster_network` and :mod:`simplify_network` solve a quadratic optimisation problem for clustering. The open-source solvers Cbc and GlPK cannot handle this. A fallback to Ipopt is implemented in this case, but requires also Ipopt to be installed. For an open-source solver setup install in your conda environment on OSX/Linux

Set Up the Default Configuration
PyPSA-Eur has several configuration options that must be specified in a config.yaml file located in the root directory. An example configuration config.default.yaml is maintained in the repository. More details on the configuration options are in :ref:`config`.

.. code:: bash
.../pypsa-eur % cp config.default.yaml config.yaml
Users are advised to regularly check their own config.yaml against changes in the config.default.yaml when pulling a new version from the remote repository.
