onnxruntime-GetInputName-API-update

问题描述

1. GetInputName 和 GetOutputName 接口从 1.12 升级到 1.13 之后，变成了 GetInputNameAllocated 和 GetOutputNameAllocated

2. 新接口返回值是 Ort::AllocatedStringPtr ，其是 std::unique_ptr<char, detail::AllocatedFree> 的别名。

3. 要注意 unique_ptr 出了 scope 之后就会自动释放其持有的资源，就会造成这样的问题：

解决方法（from the issue above）：

std::vector<const char*> inputNodeNames; //
std::vector<AllocatedStringPtr> inputNodeNameAllocatedStrings; // <-- newly added
...
...
auto inputNodesNum = session->GetInputCount();
for (int i = 0; i < inputNodesNum; i++) {
	auto input_name = session->GetInputNameAllocated(i, allocator);
	inputNodeNameAllocatedStrings.push_back(std::move(input_name));
	inputNodeNames.push_back(inputNodeNameAllocatedStrings.back().get());
}
