I just shipped retrain-pipelines 0.1.1 today. The doc is also pimped compared to previous release. That was clearly not mature then. I'll have to focus on another project for the next couple weeks but, anyone feel free to open issues on the GitHub repo and discuss any interest you'd have there if you will (please?) ! In the meantime, you may enjoy retrying this : https://huggingface.co/blog/Aurelien-Morgan/stateful-metaflow-on-colab
I just published the first article in a pair. I could make it a longer tailed series, in case you liked em. This one dives into self-hosting Metaflow without needing S3, illustrated with a version tailored for Google Colab. find it @ https://huggingface.co/blog/Aurelien-Morgan/stateful-metaflow-on-colab
