Sets a constant input for an operator and specifies the memory address for storing the input tensor data and address length.

aclError aclSetTensorConst(aclTensorDesc *desc, void *dataBuffer, size_t length)

Parameter	Input/Output	Description
desc	Output	Pointer to data of the aclTensorDesc type. Call aclCreateTensorDesc to create data of the aclTensorDesc type in advance.
dataBuffer	Input	Pointer to the memory address of the input tensor data. In Ascend EP form, allocate memory on the host. In Ascend RC form, allocate memory on the device. In Open Ctrl CPU form, allocate memory on the device. For details about the memory allocation APIs, see Memory Management.
length	Input	Length of the memory address, in bytes.
