Thanks for sending an issue! Please fill in the following template to help quickly solve your problem.

Describe the current behavior / 问题描述 (Mandatory / 必填)

1. aclnnNonzero.md：示例代码存在不可达代码。main 函数在『return 0;』之后才编写『7. 释放device资源』块（aclrtFree/aclrtDestroyStream/aclrtResetDevice/aclFinalize），该块永远无法执行，device 资源与运行时不会按示例意图释放。
2. aclnnNonzeroV2.md：示例代码中输出张量形状与数据大小设置错误。输入全为非零元素（N=8），输出shape应为{2, 8}，size应为16，当前代码设置为{2, 7}和14。

Describe the expected behavior / 预期结果 (Mandatory / 必填)

1. 将『return 0;』移到『7. 释放device资源』块之后，确保 aclrtFree(selfDeviceAddr)/aclrtFree(outDeviceAddr)/aclrtDestroyStream/aclrtResetDevice/aclFinalize 在返回前执行。
2. std::vector<int64_t> outShape = {2, 8};
   void* selfDeviceAddr = nullptr;
   void* outDeviceAddr = nullptr;
   aclTensor* self = nullptr;
   aclTensor* out = nullptr;
   std::vector selfHostData = {0, 1, 2, 3, 4, 5, 6, 7};
   std::vector<int64_t> outHostData(16, 0);
