To install rake as a package, run:
python setup.py install
from nlp_rake import rake
import nltk
rakeObj = rake.Rake(stop_words_list=nltk.corpus.stopwords.words('russian'), min_char_length=4, max_words_length=3, min_keyword_frequency=2)
rake_object = rake.Rake(stoppath, 5, 3, 4)
sample_file = open("source.txt", 'r', encoding="iso-8859-1")
text = sample_file.read()
keywords = rakeObj.run(text)
# 3. print results
print("Keywords:", keywords)
