Thank you for reporting this @florentk . It seems that you are not using the code in the master branch, but an older release. "/usr/local/lib/python3.5/dist-packages/graal/backends/core/analyzers/cloc.py", line 58 is currently an empty line: https://github.com/chaoss/grimoirelab-graal/blob/master/graal/backends/core/analyzers/cloc.py#L58
