TWE-1 and TWE-3 errors

[Tellyang7]

I met these issues:
In TWE-1:
When train topic vectors: topical_word_embeddings/TWE-1/gensim/models/word2vec.py", line 901
NameError: global name 'train_sentence_topic' is not defined

In TWE-3:
TWE-3/gensim/models/word2vec.py", line 126, in train_sentence_sg
l1 = model.syn0[word2.index]
IndexError: only integers, slices (:), ellipsis (...), numpy.newaxis (None) and integer or boolean arrays are valid indices

I was so upset as so many times tried and failed, and different compile ways also have tried. Please help me.
