Hey,
I think the major issue was getting torch 2.7 working on a bare-metal installation as the app needed that and the pre-built docker containers aren't out yet for torch 2.7. Transformer Lab is also much more than just the Pytorch setup as it provides several plugins which can be used for training, evaluation, dataset generation (and much more!).
Also, the pre-built docker containers unfortunately do not work on WSL which caused the majority of the issues.
I'd love to hear if you had a different experience or if I'm mistaken in any of this!
