¿Alguien sabe cómo resolver este error de lectura de archivo enTreeTagger que es una herramienta común de procesamiento de lenguaje natural utilizada paraPOS Etiquetar, lemmatizar y chunk oraciones?

        reading parameters ...

No encontré ningún posible problema de instalación como se indica enhttp://www.ims.uni-stuttgart.de/projekte/corplex/TreeTagger/installation-hints.txt. He seguido las instrucciones en la página web y está instalado correctamente (http://www.ims.uni-stuttgart.de/projekte/corplex/TreeTagger/#Linux):

alvas@ikoma:~$ mkdir treetagger
alvas@ikoma:~$ cd treetagger

Path variables modified in tagging scripts.

You might want to add /home/alvas/treetagger/cmd and /home/alvas/treetagger/bin to the PATH variable so that you do not need to specify the full path to run the tagging scripts.

Pero cuando intento probar el software obtengo estos errores:
