i used pytorch lightning back in may when i was working on pretraining gpt2 on TPUs (https://bkkaggle.github.io/blog/nlp-research-part-2/). it was really impressive how stable it was especially given how a lot of features were still being added at a very fast pace.
also, this was probably the first (and maybe still is?) high-level pytorch library that let you train on tpus without a lot of refactoring and bugs which was a really nice thing to be able to do given how the pytorch-xla api was still unstable at that point. <3
