NLTK was unable to find stanford-parser\.jar! Set the CLASSPATH environment variable

Download them from:

stanford/stanford-parser.jar.zip

http://www.java2s.com/Code/Jar/s/Downloadstanfordparserjar.htm

stanford-parser-3.5.2-models.jar

http://central.maven.org/maven2/edu/stanford/nlp/stanford-parser/3.5.2/

And point the file paths in code.

You need to add the jars for the Stanford parser and the models to your CLASSPATH:

  1. download Stanford CoreNLP 3.8.0 (and the Chinese models jar) available here: https://stanfordnlp.github.io/CoreNLP/download.html

  2. place the Chinese models jar in the Stanford CoreNLP folder

  3. add this to your Python: 

    os.environ['CLASSPATH'] = "/path/to/stanford-corenlp-full-2017-06-09/*"

I think that should fix your issue.
