Methods¶

static void type_check(
    const Tensor& tensor,
    const std::map<std::string, std::vector<std::string>>& type_info = {}
    )

Checks OpenVINO remote type.

Parameters:

tensor	Tensor which type is checked.
type_info	Map with remote object runtime info.
Exception	if type check with specified parameters failed.

void \* data(const element::Type)

Access to host memory is not available for RemoteTensor. To access a device-specific memory, cast to a specific RemoteTensor derived object and work with its properties or parse device memory properties via RemoteTensor::get_params.

Returns:

Nothing, throws an exception.

ov::AnyMap get_params() const

Returns a map of device-specific parameters required for low-level operations with underlying object. Parameters include device/context/surface/buffer handles, access flags, etc. Content of the returned map depends on remote execution context that is currently set on the device (working scenario). Abstract method.

Returns:

A map of name/parameter elements.
