Installation and Setup
Requirements and boundary conditions
VencoPy runs on Unix and Windows-based operating systems. It requires an installed version of python and the package, dependency and environment management tool conda as well as access to the internet for setting up the environment (downloading the required packages). VencoPy is consistent with the software application class 1 of the DLR software categorization. Versioning is based on major, minor and fix (X.Y.Z) changes versioning system via git-labels. You can use VencoPy as a user or contribute to the codebase and documentation as developer. Depending on that choice the installation and setup differs.
Installation for users
As a user, you will apply VencoPy for answering analytical questions. Thus, you’re mainly interested in applying VencoPy’s built-in features and functions. On this level, you will not change the codebase within the VencoPy class objects - of course you can write your own data processing routines around those functions.
Install using the environment management system conda, open the conda console, create a new environment and activate it by typing:
conda create -n <your environment name> python=3.9 conda activate <your environment name>
Install VencoPy from the Python Package Index PyPI:
pip install vencopy
Navigate to a parent directory where you want to create your VencoPy user folder in and type:
You will be prompted for a userfolder name, type it and hit enter. Your VencoPy user folder will now be created. It will look like this:
FOLDERNAME ├── config │ ├── evaluatorConfig.yaml │ ├── flexConfig.yaml │ ├── globalConfig.yaml │ ├── gridConfig.yaml │ ├── localPathConfig.yaml │ └── parseConfig.yaml ├── output │ ├── tripConfig.yamldataParser │ ├── evaluator │ ├── flexEstimator │ ├── gridModeler │ └── tripDiaryBuilder ├── tutorials │ └── .. └── run.py
The configs in the config folder are the main interface between the user and the code. In order to learn more about them, check out our tutorials. For this you won’t need any additional data.
To run VencoPy in full mode, you will need the data set Mobilität in Deutschland (German for mobility in Germany), you can request it here from the clearingboard transport: https://daten.clearingstelle-verkehr.de/order-form.html Currently, VencoPy is only tested with the B2 data set.
In your localPathConfig.yaml, please enter the path to your local MiD STATA folder, it will end on …/B2/STATA/. Now open your user folder in an IDE, configure your interpreter (environment) or type:
and enjoy the tool!
Installation for developers
This part of the documentation holds a step-by-step installation guide for VencoPy.
Navigate to a folder to which you want to clone VencoPy. Clone the repository to your local machine using
git clone https://gitlab.com/dlr-ve/vencopy.git
Set-up your environment. For this, open a conda console, navigate to the folder of your VencoPy repo and enter the following command:
conda env create -f requirements.yml conda activate VencoPy_env
Configure your config files if you want to use absolute links. This is only needed if you want to reference your own local data or want to post-process VencoPy results and write them to a model input folder somewhere on your drive. You will find your config file in your repo under /config/config.yaml Input filenames are set to the example files shipped with the repo. You may specify labels for file naming in the config under the key “labels”.
You’re now ready to run VencoPy for the first time by typing:
