@woodsh17 thanks for taking a run at this. I am able to install with uv and run from the uv venv, but I get an error when trying to do uv run:

  × Failed to resolve dependencies for `hbdesigner` (v0.0.1)
  ╰─▶ Requirements contain conflicting URLs for package `torch` in all marker environments:
      - https://download.pytorch.org/whl/cpu/torch-2.4.1%2Bcpu-cp310-cp310-linux_x86_64.whl
      - https://download.pytorch.org/whl/cu130/torch-2.9.0%2Bcu130-cp310-cp310-manylinux_2_28_x86_64.whl

Is this an issue? I am fiddling with the pyproject.toml to try and avoid having to specify all the urls

@hdieckhaus I added conflicts to the pyproject.toml file that should fix the error when using uv run. If you already installed and have activated the virtual environment you shouldn't need to use uv run, but we still want it to work so thanks for checking on that!

@woodsh17 thanks for circling back on this, it is now working happily on my end.
