The type 'long' no longer exists under python 3. The runtime execution
of the code using it in the metrics module already detects the python
version, but when the linter is run under python 3 it does not apply
the same check. Add a noqa pragma to tell the linter to ignore the
line where 'long' is referenced to avoid an error.
