In word2vec example in basic models:
line from 54-57 should be replaced by these:
with zipfile.ZipFile(data_path) as f: text_words = f.read(f.namelist()[0]) text_words=str(text_words, encoding='ascii') text_words=text_words .lower().split()
do the encoding issue for python 3.6 and every xrange should be replaced by range as well
