Solutions

1. Ensure pyproject.toml at the repository root contains a top-level `version = "..."` entry; the script reads it with a regex matching `^version\s*=\s*"([^"]+)"`.
2. Run the script from a checkout of the docling repository so that Path(__file__).resolve().parents[1] points at the repo root containing pyproject.toml.
3. Check that pyproject.toml is readable and that its [project] section declares a plain `version` string rather than dynamic versioning.

When it happens

Trigger: Raised by perfs/xlsx_merged_cells.py when the benchmark script cannot parse a version string out of the repository's pyproject.toml.

Common situations: Running the benchmark from a copied or partial checkout where pyproject.toml is missing, unreadable, or does not contain a 'version = "..."' line.
