exp show: sort commits

[dberenbaum]

It's currently only possible to sort experiments within their parent commit, but it can also be useful to sort the actual commits, tags, or branches themselves. It would be nice to have some option like --sort-commits, --sort-parents, or similar.

See https://discuss.dvc.org/t/dvc-exp-show-experiment-not-showing-wrong-position/1019/1

@shcheklein @tapadipti What do you think about this for Studio? Have you seen any requests to sort across branches?

[shcheklein]

The only slightly related one is this one iterative/studio-support#44 . That's all that comes to my mind, @dberenbaum . May be Tapa can remember more.

btw, @mattseddon I think we decided in VS Code to sort actual parents (and keep checkpoints as-is) or what is the current mode?

That's correct, we only sort experiments and leave their checkpoints alone.

[dberenbaum]

Sorry for being unclear, this is not related to checkpoints. By parent commit, I mean the branch, tag, or regular Git commit from which the experiment originated.

For example:

  Experiment                Created        dvclive.json:epoch   dvclive.json:mult   step

Not the best example, but this is about sorting between exp, main, and mynewexp. Not sure if that's relevant for VS Code, or if you always show only experiments based on the current workspace.

[mattseddon]

Right now we only show experiments for the current workspace. This would be a future question/problem for us, not immediate 👍🏻 .

There's another one related to comparing results across branches (https://github.com/iterative/cse/issues/17). But this also isn't about sorting across branches.

Not in current plans
