pyproject.toml missing project.version -> causes error adding to uv managed environments.

[shinstra-intranel]

Cannot add label-studio-sdk to uv managed python environment due to missing version field in the pyproject.toml.

  × Failed to download and build `label-studio-sdk @ git+https://github.com/HumanSignal/label-studio-sdk.git`

        | ^^^^^^^^^
      `pyproject.toml` is using the `[project]` table, but the required `project.version` field is neither set    
      nor present in the `project.dynamic` list

This issue seems to be related to adding label-studio-ml backend to the environment.

• An env with just label-studio + sdk runs fine.
• local copies of the sdk (project.version field added) + ml_backend (sdk dependency changed to version instead of git url in requirements) works.
• haven't managed to get label-studio + sdk + ml_backend running within the same uv environment yet.

Hello,

How do you have enviorment setup? Are you using conda or venv enviorment? Do you use pip or poetry?

Thank you,
Abu

I'm using uv (https://docs.astral.sh/uv/)

Examples:

uv init .
uv add label-studio
uv add git+https://github.com/HumanSignal/label-studio-ml-backend

These both implicitly depend on the sdk

This throws an issue with the format of the toml file in this library as shown above, preventing it from building the environment.

Digging into this a bit deeper, it actually might be more of an issue with the way the label-studio-ml-backend is setup. sdk releases add fine - the ml-backend however points to this url instead of a version.

Hi there,

My apologies for the delay here. We released an update that added the project.dynamic field within pyproject.toml, in order to include the necessary version information. Could you please let me know if you're still seeing this issue after updating to the latest release?
