expected to be used for small values of n, so z can
      approximate t.
  The significant figure estimation used in conjunction with the
  *trim_sigfig* method to provide a more human interpretable data
  summary. __repr__ does not use this method; it simply displays
  raw values. Significant figure estimation is intended for
  *Compare*.

class torch.utils.benchmark.CallgrindStats(task_spec, number_per_run, built_with_debug_symbols, baseline_inclusive_stats, baseline_exclusive_stats, stmt_inclusive_stats, stmt_exclusive_stats, stmt_callgrind_out)
Top level container for Callgrind results collected by Timer.
Manipulation is generally done using the FunctionCounts class,
   which is obtained by calling CallgrindStats.stats(...). Several
   convenience methods are provided as well; the most significant is
   CallgrindStats.as_standardized().
as_standardized()
  Strip library names and some prefixes from function strings.
