How many lines of code does PyTorch consist of?

How many lines of code has PyTorch in opensource? Approximately. How many manpower (measured in man hours) were spent to make PyTorch? Answer to 2nd question optional. Thanx

I think git ls-files | xargs wc -l should work, which shows 220718 lines in total.
You could adapt this command to filter specific file types etc. if needed.
