ABCpy requires Python3 and is not compatible with Python2. The simplest way to install ABCpy is via PyPI and we recommended to use this method.
Simplest way to install
pip3 install abcpy
This clearly works also in a virtual environment.
If you prefer to work on the source, clone the repository
git clone https://github.com/eth-cscs/abcpy.git
Make sure all requirements are installed
cd abcpy pip3 install -r requirements.txt
To create a package and install it, do
make package pip3 install build/dist/abcpy-0.5.4-py3-none-any.whl
Note that ABCpy requires Python3.
