pybpmn-parser 0.1.1

Add a short description here!

pybpmn-parser

Starter code for using the hdBPMN dataset for diagram recognition research.

The dump_coco.py script can be used to convert the images and BPMN XMLs into a COCO dataset. COCO is a common format used in computer vision research to annotate the objects and keypoints in images.

python scripts/dump_coco.py path/to/hdBPMN path/to/target/coco/directory/hdbpmn

Moreover, the demo.ipynb Jupyter notebook can be used to visualize (1) the extracted bounding boxes, keypoints, and relations, and (2) the annotated BPMN diagram overlayed over the hand-drawn image. Note that the latter requires the bpmn-to-image tool, which in turn requires a nodejs installation.

Installation

pip install pybpmn-parser

Development

In order to set up the necessary environment:

1. create an environment pybpmn-parser with the help of conda:

   conda env create -f environment.yml
   

2. activate the new environment with:

   conda activate pybpmn-parser
   

NOTE: The conda environment will have pybpmn-parser installed in editable mode. Some changes, e.g. in setup.cfg, might require you to run pip install -e . again.

Optional and needed only once after git clone:

3. install JupyterLab kernel

   python -m ipykernel install --user --name "${CONDA_DEFAULT_ENV}" --display-name "$(python -V) (${CONDA_DEFAULT_ENV})"
   

4. install several pre-commit git hooks with:

   pre-commit install
   # You might also want to run `pre-commit autoupdate`
   

   and checkout the configuration under .pre-commit-config.yaml. The -n, --no-verify flag of git commit can be used to deactivate pre-commit hooks temporarily.
