ModuleNotFoundError: No module named 'dataclasses'`

It's likely due to not being on Python 3.6+.

Try this with e.g. Python 3.7. In the terminal:

conda create --name py37 anaconda python=3.7 --yes
conda activate py37
pip install efficient-apriori
python -c "import efficient_apriori as e; print(e.__version__)"
