Lightning-AI/pytorch-lightning has 50,462 source lines of code out of 72,408 total lines across 365 files, counted from the 320e79704a9e921b3a11d8a1d1ba685e6b7ebc69 ref at commit 320e79704a9e by the OctoCounts tokei engine on 2026-09-17. The report is cached by commit, tokei version, and analysis options, so recounting the same revision returns exactly these numbers.

OctoCounts produced this report by resolving Lightning-AI/pytorch-lightning to commit 320e79704a9e, downloading the repository source archive, and counting every source file with tokei, the open-source line counter written in Rust. The table below breaks the count down by programming language into files, total lines, code lines, comment lines, and blank lines, so the figures can be compared across languages and projects. Results are cached by commit, tokei version, and analysis options, so counting the same revision again reproduces exactly these numbers.
