torch and lua not fit for any of the updated ubuntu machines

[petrichor1998]

Hello to the maintainers of this repository. I have been trying to use this code but it is such a big pain to install torch and lua on my Ubuntu 22.04. I strongly suggest you guys to use pytorch instead to write your code. It is way more convenient and accessible. Please help people like me out and release the pytorch code. I will have to see if there are any other models available on the internet for image captioning. What is even the point of having such a good model if no-one can use it.
