Detailed Documentation¶

This class represents the main Data representation node.

The NN graphs are di-graphs consisting of data nodes and layer nodes.

Construction¶

Data(const std::string& name, Precision _precision, Layout layout = NCHW)

An empty constructor (dimensionless)

Parameters:

name	Name of the data node
_precision	Precision of the data
layout	Data layout

Data(const std::string& name, const TensorDesc& desc)

A constructor with tensor descriptor.

Parameters:

name	Name of the data node
desc	Tensor descriptor

Data(const Data& data)

A copy constructor.

Parameters:

data	A data object to copy from

Methods¶

Data& operator = (const Data& data)

An assignment operator.

Parameters:

data	A data object to copy from

Returns:

An assigned object

bool isInitialized() const

Checks if the current node is resolved.

Returns:

true if resolved, false otherwise.

void setDims(const SizeVector& a_dims)

Sets the data dimensions.

After the current node is marked as resolved.

Parameters:

a_dims

Tensor dimensions to set

void setLayout(Layout layout)

Sets the layout value for this Data instance.

Parameters:

layout

Layout value to set

void reshape(const SizeVector& dims, Layout layout)

changes dims and layout at same time

Parameters:

dims	new dimensions
layout	new layout

void reshape(const std::initializer_list<size_t>& dims, Layout layout)

changes dims and layout at same time

Deprecated Use InferenceEngine::Data::reshape(const SizeVector&, Layout)

Parameters:

dims	new dimensions
layout	new layout

Layout getLayout() const

Gets the layout value for this Data instance.

Returns:

Layout

const TensorDesc& getTensorDesc() const

Gets Tensor descriptor reference.

Returns:

reference to TensorDesc

const Precision& getPrecision() const

Gets a precision type of this Data instance.

Returns:

Precision type

void setPrecision(const Precision& precision)

Sets a precision type of this Data instance.

Parameters:

precision

Precision of the data

const SizeVector& getDims() const

Returns:

data dimensions

const std::string& getName() const

Returns:

name of the data object

void setName(const std::string& newName)

Sets a name the Data object.

Parameters:

newName

Name of the data node

const UserValue& getUserObject() const

Returns:

convenient arbitrary user data holder
