In monorepo: Incorrect link to Studio view

[mnrozhkov]

Bug Report

I'm testing DVC Experiments for monorepo scenario using this repo. I encountered unexpected behavior for dvc exp push

Within a mono repo say we have:

- / 
  - project_a
  - project_b
  - root_content

In Studio, I created a project for project_a subdir. When working inside project_a, I run dvc exp push, but the generated link is not correct!

➜  ~/dev/test/monorepo-multiproject-detached-exps/project_a|main⚡ ⇒  dvc exp push origin -A

Thanks @mnrozhkov! As mentioned in Notion, I'm not sure how DVC can handle this (we would probably need to change the Studio API), but let's keep it open so we have a record and can come back to it.

[dberenbaum]

Also, I notice you have duplicate experiment names being shown (like pucka-navy and pucka-navy). Do you know how you got that?

[mnrozhkov]

dvc exp push origin -A

It's interesting, I didn't notice that. I guess it's because of the same reason - some operations have a scope of DVC project dir, but other not.

• to run dvc exp list I need to be inside project_a or project_b (I can't run it in the repo root)

• but after I run dvc exp run, both projects show the same experiment list

• with command dvc exp push origin only a single experiment push mentioned in the log

• with command dvc exp push origin -A I can reproduce this behavior

@mnrozhkov can you run this command in that git repo and post the output (it shouldn't matter which dvc subrepo you are in)

git show-ref pucka-navy

[mnrozhkov]

@pmrowla I removed the previous experiment. Below is the similar behavior with ninth-whin exp
