Hello! I'm one of the creators of Fomoro and this is something we've been building over the last couple of weeks. I have a Macbook Pro with no GPU so I frequently use AWS to train models. While AWS doesn't have the best GPUs for deep learning they're still faster than without and as an added benefit I could train as many as I want simultaneously.
Right now, Fomoro simplifies training on spot instances, it's a little rough around the edges but try it out and let me know what you think. Thanks!
