Function Documentation

gst_tensor_sparse_from_dense()

GstMemory* gst_tensor_sparse_from_dense	(	GstTensorMetaInfo *	meta,
		GstMemory *	mem
	)

Make sparse tensor with input dense tensor.

Parameters

[in,out]	meta	tensor meta structure to be updated
[in]	mem	gst-memory of dense tensor data

Returns

pointer of GstMemory with sparse tensor data or NULL on error. Caller should handle this newly allocated memory.

alloc maximum possible size of memory

Consider using macro to reduce loc and readability

update meta nnz info

write to output buffer

add meta info header
