Usually this error means that you forgot to include "self" in the
method signature.  As a result it receives two arguments (self and
bench) but only has one defined (bench).

The snippet you posted looks correct, though.  It might be easier to
help if you posted the actual code.  Also the full stack trace might
be helpful.
