The data download links for the scalar plugin currently only support downloading one single run. In a situation where many runs are used to compare different hyperparameters, it would be nice to be able to download all runs simultaneously into a single file. Maybe even a download all scalars button, that gives a zip archive with all the scalar graphs. This would also allow to quickly share the most essential data of an experiment without having to copy multiple gigabytes of log files.

I think it would make sense at least for the drop-down menu on each chart to have an (all) option that would download data for all runs.

It might also make sense to have a button for downloading data for all charts too, though this could get a little more complex - since not all charts are rendered on the frontend, e.g. ones on later pages, so it might make more sense to produce the zip file at the backend, but then the question comes up of whether or not the run selection settings at the frontend need to be propagated to the backend, etc.

We're also still working on better hyperparameter support, so when that lands that might include some dedicated data download options that are better suited for the hyperparameter search use case.

Will the TensorBoard developers implement a "download all runs" option? This has been labeled as "contributions welcome" but this is a feature that would be very helpful.

Hi, just wondering if there has been any update? Would be a really appreciated feature!
