      #   Different platforms will have subtly different behavior for Python
      #   tracing. Observed differences include:
      #     1) Windows symbolicates names differently from posix
      #     2) The profile callback for c_call does not fire for Tensor.__pow__
      #        on certain platforms. This is not caused by the function tracer,
      #        but by cPython itself.
      #
      # The purpose of these unit tests is to ensure that the profiler is
      # doing reasonable things. When these platform dependent variations occur
      # simply coerce them into a platform independent form. If you made a
      # change in the codebase which changes the trace produced, simply use
      # EXPECTTEST_ACCEPT=1 to update the tests to reflect the new structure.
  
      # expecttest will not show the diff view if `len(actual) < len(expected)`
