  ModuleNotFoundError: No module named 'pkg_resources'

  hint: This error likely indicates that `flatdict@4.0.1` depends on `pkg_resources`, but doesn't declare it as a build dependency. If `flatdict` is a first-party package, consider adding `pkg_resources` to its `build-system.requires`.
  Otherwise, either add it to your `pyproject.toml` under:

  [tool.uv.extra-build-dependencies]
  flatdict = ["pkg_resources"]

  or `uv pip install pkg_resources` into the environment and re-run with `--no-build-isolation`.

help: flatdict (v4.0.1) was included because sim-evals (v0.1.0) depends on isaaclab (v2.2.0) which depends on flatdict
