Currently ElphonPy does not have a distributable, but this repository can be directly cloned to your home directory and import into your python files or Jupyter notebook as follows:
import sys
sys.path.append('PATH-TO-ELPHONPY')
Prerequisite packages: pymatgen, numpy, matplotlib.pyplot
Programs that are used in some ElphonPy functions:
read_relax_output --> pwo2xsf.sh (found in ~/qe-installation/PW/tools, and should be added to your .bashrc PATH.)
