Example

// Use FreeTensor to release the tensors allocated by AllocTensor. Note that FreeTensor needs to be used together with AllocTensor.
AscendC::TPipe pipe;
AscendC::TQueBind<AscendC::TPosition::VECOUT, AscendC::TPosition::GM, 2> que;
int num = 4;
int len = 1024;
pipe.InitBuffer(que, num, len);
AscendC::LocalTensor<half> tensor1 = que.AllocTensor<half>();
que.FreeTensor<half>(tensor1);
