Stanford Parser を Python の NLTK と統合するにはどうすればよいですか?

import os
from nltk.parse import stanford

# Set environment variables to specify jar paths
os.environ['STANFORD_PARSER'] = '/path/to/standford/jars'
os.environ['STANFORD_MODELS'] = '/path/to/standford/jars'

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

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

# GUI visualization
for line in sentences:
    for sentence in line:
        sentence.draw()
