eTraGo is designed as a Python package therefore it is mandatory to have Python 3 installed. If you have a working Python3 environment, use pypi to install the latest eTraGo version. We highly recommend you to use a virtual environment. Use following pip command in order to install eTraGo.
$ pip3 install eTraGo
Using a virtual environment¶
Before installing eTraGo, you create a virtual environment (where you like it) and activate it:
$ virtualenv venv --clear -p python3.5 $ source venv/bin/activate $ cd venv
Inside your activated virtual environment you can install eTraGo with the pip command, as previously explained.
Linux and Ubuntu¶
The Package eTraGo is tested with Ubuntu 16.04 and 18.04 inside the virtual environments of virtualenv. The installation is shown above.
Windows or Mac OSX users¶
For Windows and/or Mac OSX user we highly recommend to install and use Anaconda for you Python3 installation. First install anaconda inclusing python 3.5 or higher version from https://www.anaconda.com/download/ and open an anaconda prompt as administrator and run:
$ conda config --add channels conda-forge $ conda install shapely $ pip install eTraGo
The full Documentation can be found on this page . We use Anaconda with an own environment in order to reduze problems with Packages and different versions on our system. Learn more about Anacona environments.
Setup database connection¶
The package ego.io will be installed
automatically when eTraGo is installed. The
gives you python SQL-Alchemy representations of
and access to it by using the
oedialect, which is a SQL-Alchemy binding
Python package for the REST-API used by the OpenEnergy Platform (OEP).
In order to connect eTraGo via the oedialect with the oedb you
have to create an account at
You can name the ‘db’
argument of the ‘args’ of the
as you wish. Once the
etrago.appl.etrago() is executed you will be asked
to enter how you want to connect to which database. If you want to use
the oedialect enter the following connection parameter. For <username> and
<token> you have to take your credentials which you obtained by registering
Your API access / login data will be saved in the folder
.egoio in the file
config.ini. Consequently, in the config.ini you can also change
your connection parameters or add new ones.
In the following you can see how the config.ini looks like when you use the
oedialect, a local postgresql database or the old psycopg2 developer connection.
Once you have created a connection (which is saved in the config.ini) you do not have to enter the connection parameter again. The software will take the connection parameter which corresponds to the entry at the ‘db’ argument.
[oedb] dialect = oedialect username = <username> database = oedb host = openenergy-platform.org port = 80 password = <token>
Local database connection¶
[local] username = YourOEDBUserName database = YourLocalDatabaseName host = localhost or 127.0.0.1 port = 5433 pw = YourLocalPassword
Old developer connection¶
[oedb] username = YourOEDBUserName database = oedb host = oe2.iws.cs.ovgu.de port = 5432 pw = YourOEDBPassword
