How to get the word back from the index, from lookup matrix?

I used a twitter dataset and used torchtext for some pre-processing, used -

TEXT.build_vocab(trn, min_freq = 2, vectors=GloVe(name='6B', dim=300))

now, I pass it through an autoencoder, and generate the same seq again. My question is If print the output of the model, it will print the indices of the words, but I would like to print the word itself. Any idea how do I go about doing that?

Answer is in the comments.
I figured it out.
