caption.py:IndexError: tensors used as indices must be long, byte or bool tensors

[AndreSun98]

When I run caption.py,I got the following error:
Traceback (most recent call last):
File "D:/2021/sjt/code/a-PyTorch-Tutorial-to-Image-Captioning-master/caption.py", line 217, in

I have the same problem. Have you solved it？

    prev_word_inds = top_k_words / vocab_size

You can try changing the "/" in the above code to "//".
