In theory, no. But for any decent performance, you need a big CUDA capable GPU, as far as I know.
But you can try it on a CPU of course. (Maybe with some modifications; see this: https://news.ycombinator.com/item?id=20977776 ; also if someone can get it working in Google Colab you get a GPU capable instance for free.)
