logging.h:309 onnxruntime::logging::LoggingManager::DefaultLogger Attempt to use DefaultLogger but none has been registered.

[Positronx]

Describe the issue

My goal is to load an onnx::ModelProto into an onnxruntime::Model. To use the method onnxruntime::Mode::Load I need a Logger. I tried to create a LoggingManager manually but the method didn't seem to work. Then, I used test/unittest_main/test_main.cc code to create an ort_env that is used to create a DefaultLoggingManager. However, I encountered the exception mentioned in the title.

To reproduce

#include "core/graph/model.h"
#include "core/session/onnxruntime_cxx_api.h"
#include "test/util/include/test_environment.h"
#include "core/session/environment.h"
#include <iostream>
#include <fstream>

std::unique_ptr<std::istream> LoadModelStream(const std::string& model_path) {
    auto input = std::make_unique<std::ifstream>(model_path, std::ios::binary);
    if (!input->is_open()) {
        std::cerr << "Failed to open the file: " << model_path << std::endl;
        return nullptr;
    }

    return input;
}
std::unique_ptr<Ort::Env> ort_env;
using namespace onnxruntime;
int main()
{
    OrtThreadingOptions tpo;
    ort_env.reset(new Ort::Env(&tpo, ORT_LOGGING_LEVEL_WARNING, "Default"));

    const std::string base_model_path = R"(.\BaseModel\base_mlp_model.onnx)";   
    auto base_model_stream = LoadModelStream(base_model_path);

    auto& loggingManager = test::DefaultLoggingManager();
    
    try
    {
        auto logger_ptr = std::make_unique<logging::Logger>(loggingManager.DefaultLogger());
    }
    catch (const std::exception& e)
    {
        std::cout << e.what() << std::endl;
        return EXIT_FAILURE;
    }
    auto logger_ptr = std::make_unique<logging::Logger>(loggingManager.DefaultLogger());

    logger_ptr->SetSeverity(logging::Severity::kINFO);
    ONNX_NAMESPACE::ModelProto model_proto;
    std::shared_ptr<Model> model;
    ORT_THROW_IF_ERROR(Model::Load(*base_model_stream, &model_proto));

    try
    {
        ORT_THROW_IF_ERROR(Model::Load(model_proto, model,
            nullptr,
            *logger_ptr));
    }
    catch (const std::exception& e)
    {
        std::cout << e.what() << std::endl;
        return EXIT_FAILURE;
    }

    ort_env.reset();
}

When I run the code above, I run into the following exception in the first try catch clause :
logging.h:309 onnxruntime::logging::LoggingManager::DefaultLogger Attempt to use DefaultLogger but none has been registered.

auto env = new Ort::Env(&tpo, ORT_LOGGING_LEVEL_WARNING, "Default");

keep this variable in memory until your program finish will solve the problem.
