// Use AllocTensor to allocate tensors.
AscendC::TPipe pipe;
AscendC::TQue<AscendC::TPosition::VECOUT, 2> que;
int num = 4;
int len = 1024;
pipe.InitBuffer(que, num, len); // Four memory blocks are allocated by InitBuffer, and the size of each memory block is 1024 bytes.
AscendC::LocalTensor<half> tensor1 = que.AllocTensor<half>(); // The length of the tensor allocated by AllocTensor is 1024 bytes.
