Python에서 Stanford Parser를 NLTK와 어떻게 통합할 수 있나요?

import os
from nltk.parse import stanford

# Specify paths to Stanford Parser and models
os.environ['STANFORD_PARSER'] = '/path/to/standford/jars'
os.environ['STANFORD_MODELS'] = '/path/to/standford/jars'

# Initialize the Stanford Parser
parser = stanford.StanfordParser(model_path="/location/of/the/englishPCFG.ser.gz")

# Parse a list of sample sentences
sentences = parser.raw_parse_sents(("Hello, My name is Melroy.", "What is your name?"))
print sentences

# Visualize the dependency tree
for line in sentences:
    for sentence in line:
        sentence.draw()

[Tree('ROOT', [Tree('S', [Tree('INTJ', [Tree('UH', ['Hello'])]),
Tree(',', [',']), Tree('NP', [Tree('PRP$', ['My']), Tree('NN',
['name'])]), Tree('VP', [Tree('VBZ', ['is']), Tree('ADJP', [Tree('JJ',
['Melroy'])])]), Tree('.', ['.'])])]), Tree('ROOT', [Tree('SBARQ',
[Tree('WHNP', [Tree('WP', ['What'])]), Tree('SQ', [Tree('VBZ',
