Sagemaker is fine an almost good once you learn the incantations that Amazon won’t document. I’m not sure why it’s all several years out of date. Maybe I should do some write-ups on my blog?

I was so close to having it working, then it needed a quota change to be able to run GPU-optimised Jupyter kernels, so I used the tool, and last I checked I'm still waiting on that. I'm going to copypasta the code cells into a .py file and push containers to ECR from my local machine, I'm tired.
