Installation

1- Download and install miniconda from: https://docs.conda.io/en/latest/miniconda.html

2- Update conda in a terminal window or anaconda prompt:

conda update conda

3- Create a new environment for swolfpy:

conda create --name swolfpy python=3.9 graphviz

4- Add Graphviz executables to your system PATH (This step is optional; Enables plotting SWM network). You can find Graphviz executables in \\miniconda3\\envs\\swolfpy\\Library\\bin\\graphviz folder or search for dot.exe file in your system. Add the directory to the Path variable in your environment variables.

5- Activate the environment:

conda activate swolfpy

6- Install swolfpy in the environment:

pip install swolfpy

7- Open python to run swolfpy:

python

8- Run swolfpy

• In terminal:

  swolfpy
  # or
  python -m swolfpy

• In python:

  import swolfpy as sp
  sp.SwolfPy()
