问题日志及出现问题的操作流程

在一个class里面初始化成员变量，通过SetData方式创建FDtensor，获取tensor的值正常。在该class的其他成员函数再次获取tensor值的时候，结果发生了变化。
参考代码如下

    std::vector<float> yaw_(120);
    std::iota(yaw_.begin(),yaw_.end(),0);
    yaw_idx_.SetData({120}, FDDataType::FP32, yaw_.data());
    yaw_idx_.PrintInfo();
    std::vector<float> data;
    data.resize(yaw_idx_.Numel());
    std::memcpy(data.data(), yaw_idx_.Data(), yaw_idx_.Nbytes());

    for(size_t i=0; i<data.size();i++){
        std::cout<<data[i]<<",";
    }

两次调用上述代码块，得到的结果不一致

Start by reproducing the shown C++ sequence that calls SetData, Data, Numel, Nbytes, and PrintInfo twice on the same FDTensor. Inspect the tensor's external data ownership and lifetime around repeated reads; done when the second read reliably matches the initialized values.
