I posted a current textbook on using transformer models with graph structures at https://lists.cpunks.org/pipermail/cypherpunks/2021-December/093166.html . The link to the book from that threads was http://library.lol/main/1BEBBF5A91CE94A5F2D5C50935BBAC9E . The book uses math notation and may skip reinforcement learning, but appears a great read. I posted a link to a market for access to systems with high-end gpus at https://lists.cpunks.org/pipermail/cypherpunks/2021-December/093292.html . The link was https://vast.ai/ . I believe this market is heavily used by entrepreneurs, researchers, etc. Most of that is happening on discord and twitter. Big resources I've been exposed to include https://colab.research.google.com/ https://www.paperspace.com/ https://huggingface.co/ https://www.gradio.app/ The TPU Research Cloud program generally accepts applicants without access otherwise, even if they are not formal researchers. The reward is access to high-end research machines on google's colab service for 30 days, starting when you choose: https://sites.research.google/trc/about/
