The installation instructions incorrect. The entire py directory from the compilation output should be copied into the netlogo extension directory, and not just the two files mentioned "If compilation succeeds, py.jar will be created. This file and pyext.py should then be placed in a folder named py in your NetLogo extensions directory."
