class nbla::Unique
-
template<typename T>
class Unique : public nbla::BaseFunction<bool, int, bool, bool, bool, bool> Find the unique elements of input array.
Inputs:
x: A N-D array.
Outputs:
y: A N-D array.
indices: A 1-D array. It’s indices of `y` elements first occurance in `x`. If `flatten` is True, it contains indices to flattend input array `x`. If `flatten` is False and `axis` is specified, it contains indices to input array `x` on `axis`.
inverse_indices: A 1-D array. It’s indices of `x` elements corresponding to `y`. If `flatten` is True, it contains indices to output array `y`. If `flatten` is False and `axis` is specified, it contains indices to output array `y` on `axis`.
counts: A 1-D array. It’s the count of each element of ‘y’ in input array `x`.
- Param flatten:
If True, unique values of the flatten input array are returned.
- Param axis:
If flatten is True and axis is specified, unique slices along axis are returned.
- Param sorted:
If True, unique values/slices sorted in ascending order are returned.
- Param with_index:
If True, `indices` is returned.
- Param with_inverse:
If True, `inverse_indices` is returned.
- Param with_counts:
`counts` is returned.
Public Functions
-
inline virtual shared_ptr<Function> copy() const
Copy another instance of Function with the same context.
-
inline virtual int min_inputs()
Get minimum number of inputs.
This is meant to be used in setup function with in_types which is used to get maximum number of inputs.
-
inline virtual int min_outputs()
Get minimum number of outputs.
This is meant to be used in setup function with out_types which is used to get max number of outputs.
-
inline virtual vector<dtypes> in_types()
Get input dtypes.
Last in_type will be used repeatedly if size of in_types is smaller than size of inputs
-
inline virtual vector<dtypes> out_types()
Get output dtypes.
Last out_type will be used repeatedly if size of out_types is smaller than size of outputs
-
inline virtual vector<string> allowed_array_classes()
Get array classes that are allowed to be specified by Context.
-
inline virtual string name()
Get function name in string.
