Function Usage

Creates a handle to an operator.

To destroy a handle, call acl.op.destroy_handle.

Prototype

C Prototype

aclError aclopCreateHandle(const char *opType, int numInputs,int numInputs, const aclTensorDesc *const inputDesc[], int numOutputs, const aclTensorDesc *const outputDesc[], const aclopAttr *opAttr, aclopHandle **handle)

Python Function

handle, ret = acl.op.create_handle(op_type, input_desc, output_desc, op_attr)

Parameter Description

Parameter	Description
op_type	Str, operator type name.
input_desc	Int list, description of the operator input tensor.
output_desc	Int list, description of the operator output tensor.
op_attr	Int, pointer address of an operator attribute. This object is created by calling acl.op.create_attr.

Return Value Description

Return Value	Description
handle	Int, operator handle address object.
ret	Int, error code. 0 indicates success. Other values indicate failure.

Return Value

Description

handle

Int, operator handle address object.

ret

Int, error code.

0 indicates success.
Other values indicate failure.

Restrictions

If an operator has a constant input but acl.set_tensor_const has not been called to set the constant input, call acl.set_tensor_place_ment to set the placement attribute of TensorDesc and set mem_type to the host memory.
