Definition at line 45 of file Comparator.h.

Constructor & Destructor Documentation

Comparator()

nnfw::misc::tensor::Comparator::Comparator ( const std::function< bool(float lhs, float rhs)> &  fn )

inline

Construct a new Comparator object.

Parameters

[in]

fn

Function that compares two float values

Definition at line 52 of file Comparator.h.

                                                                : _compare_fn{fn}

    // DO NOTHING
  }

Member Function Documentation

compare()

std::vector< Diff< float > > nnfw::misc::tensor::Comparator::compare	(	const Shape &	shape,
		const Reader< float > &	expected,
		const Reader< float > &	obtained,
		Observer *	observer = nullptr
	)		const

Compare two tensors.

Parameters

[in]	shape	Shape of two tensors
[in]	expected	Reader<float> object that accesses expected tensor
[in]	obtained	Reader<float> object that accesses obtained tensor
[in]	observer	Observer notified of expected value and obtained value at every index

Returns

std::vector<Diff<float>> containing information of failed comparison

Definition at line 29 of file Comparator.cpp.

{
  std::vector<Diff<float>> res;
 
  zip(shape, expected, obtained) <<
    [&](const Index &index, float expected_value, float obtained_value) {
      if (!_compare_fn(expected_value, obtained_value))
      {
        res.emplace_back(index, expected_value, obtained_value);
      }
 
      // Update max_diff_index, if necessary
      if (observer != nullptr)
      {
        observer->notify(index, expected_value, obtained_value);
      }
    };
 
  return res;
}
