template<typename Dtype>

void Blob< Dtype >::CopyFrom	(	const Blob< Dtype > &	source,
		bool	reshape = `false`
	)

Copy from a source Blob.

Parameters

source	the Blob to copy from
reshape	if false, require this Blob to be pre-shaped to the shape of other (and die otherwise); if true, Reshape this Blob to other's shape if necessary

template<typename Dtype>

void Blob< Dtype >::Reshape ( const vector< int > & shape )

Change the dimensions of the blob, allocating new memory if necessary.

This function can be called both to create an initial allocation of memory, and to adjust the dimensions of a top blob during Layer::Reshape or Layer::Forward. When changing the size of blob, memory will only be reallocated if sufficient memory does not already exist, and excess memory will never be freed.

Note that reshaping an input blob and immediately calling Net::Backward is an error; either Net::Forward or Net::Reshape need to be called to propagate the new input shape to higher layers.

template<typename Dtype>

void Blob< Dtype >::ShareData ( const Blob< Dtype > & other )

Set the data_ shared_ptr to point to the SyncedMemory holding the data_ of Blob other – useful in Layer&s which simply perform a copy in their Forward pass.

This deallocates the SyncedMemory holding this Blob's data_, as shared_ptr calls its destructor when reset with the "=" operator.
