Do I have to use an older version of NetLogo?

[bryanpiguave]

I just want to run this script, but this comes out
import nl4py
import os
file_to_open = os.path.join(".","spatialCOVID19-master","epiDEM COV_v13.nlogo")
path_to_netlogo = 'C:/Program Files/NetLogo 6.1.1/'
nl4py.startServer(path_to_netlogo)
ws=nl4py.newNetLogoHeadlessWorkspace()
ws.openModel(file_to_open)
ws.closeModel()
nl4py.deleteAllHeadlessWorkspaces()
nl4py.stopServer()

IndexError: pop from an empty deque
ConnectionRefusedError: [WinError 10061] No se puede establecer una conexión ya que el equipo de destino denegó expresamente dicha conexión
Py4JNetworkError: An error occurred while trying to connect to the Java server (127.0.0.1:25333)

Spyder 4.0.1
Python 3.7.4
nl4py -> last version
Java 8 -> 181

@bryanpiguave NL4Py should work with Python 3.7 . Is your PATH variable set to point to your java installation?
