Global 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 and shape. Allocate internal host storage using default allocator.

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:

type	Tensor element type
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)

Get shape for tensor.

Parameters:

shape	Tensor shape
tensor	A point to ov_tensor_t

Returns:

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

ov_tensor_get_element_type(
    const ov_tensor_t \* tensor,
    ov_element_type_e \* type
    )

Get type for tensor.

Parameters:

type	Tensor element type
tensor	A point to ov_tensor_t

Returns:

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

ov_tensor_get_size(const ov_tensor_t \* tensor, size_t \* elements_size)

the total number of elements (a product of all the dims or 1 for scalar).

Parameters:

elements_size	number of elements
tensor	A point to ov_tensor_t

Returns:

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

ov_tensor_get_byte_size(const ov_tensor_t \* tensor, size_t \* byte_size)

the size of the current Tensor in bytes.

Parameters:

byte_size	the size of the current Tensor in bytes.
tensor	A point to ov_tensor_t

Returns:

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

ov_tensor_data(const ov_tensor_t \* tensor, void \*\* data)

Provides an access to the underlaying host memory.

Parameters:

data	A point to host memory.
tensor	A point to ov_tensor_t

Returns:

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

ov_tensor_free(ov_tensor_t \* tensor)

Free ov_tensor_t.

Parameters:
