ClassNotFoundException when producing dependency parsers

[Lucho0491]

When I tried to run the cmd in the 'dependency_parse' function in preprocess_sst.py, an error occurred as follows:

Caused by: java.lang.ClassNotFoundException: edu.stanford.nlp.tagger.maxent.ExtractorNonAlphanumeric

I guess ExtractorNonAlphanumeric should exist in the corresponding directory in the stanford-parser.jar, but it is not the case actually. Can you help solve this issue? Many thanks.

Please make sure from terminal working directory, there are lib folder (https://github.com/ttpro1995/TreeLSTMSentiment/tree/master/lib)

In python code (https://github.com/ttpro1995/TreeLSTMSentiment/blob/master/scripts/preprocess-sst.py)

    # produce dependency parses
    classpath = ':'.join([
        lib_dir,
        os.path.join(lib_dir, 'stanford-parser/stanford-parser.jar'),
        os.path.join(lib_dir, 'stanford-parser/stanford-parser-3.5.1-models.jar')])
    for filepath in sent_paths:
        dependency_parse(filepath, cp=classpath, tokenize=False)

make sure it point to java lib (https://github.com/ttpro1995/TreeLSTMSentiment/tree/master/lib)
