Download Fujiyama-Renderer-0.3.6.tar.gz
Rename Fujiyama-Renderer folder

Edit.
# nano .bash_profile

LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$HOME/Fujiyama-Renderer/lib

export PATH=$PATH:/home/yourname/Fujiyama-Renderer/bin

export FJ_LIBRARY_PATH=/home/yourname/Fujiyama-Renderer/lib

creat mesh folder and ply folder and hdr folder.
copy fujiyama.py to bin folder.
$ export PYTHONPATH=$PYTHONPATH:/usr/lib/python2.7/site-packages/:$HOME/Fujiyama-Renderer/bin/

not python3.8.
Python 3 is not supported.
$ python teapot2.py

thank you.
