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
