I have tried your example code but there was an issue
File "<stdin>", line 2, in <module>
File "/home/cpu10508-local/.virtualenvs/dl4cv/lib/python3.5/site-packages/vncorenlp/vncorenlp.py", line 53, in __init__
raise FileNotFoundError('Java was not found, please install JRE or JDK 1.8 first.')
I have installed java though
>>> import os
>>> os.system("java -version")
openjdk version "1.8.0_171"
