Functions

ov_tensor_create_from_host_ptr(const ov_element_type_e type, const ov_shape_t shape, void *host_ptr, ov_tensor_t **tensor)#

Constructs Tensor using element type, shape and external host ptr.

Parameters:

  • type – Tensor element type

  • shape – Tensor shape

  • host_ptr – Pointer to pre-allocated host memory

  • tensor – A point to ov_tensor_t

Returns:

Status code of the operation: OK(0) for success.

ov_tensor_create(const ov_element_type_e type, const ov_shape_t shape, ov_tensor_t **tensor)#

Constructs Tensor using element type and shape. Allocate internal host storage using default allocator.

Parameters:

  • shape – Tensor shape

  • tensor – A point to ov_tensor_t

Returns:

Status code of the operation: OK(0) for success.

ov_tensor_set_shape(ov_tensor_t *tensor, const ov_shape_t shape)#

Set new shape for tensor, deallocate/allocate if new total size is bigger than previous one.

Parameters:

  • shape – Tensor shape

  • tensor – A point to ov_tensor_t

Returns:

Status code of the operation: OK(0) for success.

ov_tensor_get_shape(const ov_tensor_t *tensor, ov_shape_t *shape)#
