ok... i solved it!!

in windows. Ort::Session 's second parameter is "const wchar_t*"

we need to make function stringToWString

edit FeatureTensor.h

Ort::Session session_{env, k_feature_model_path.c_str(), Ort::SessionOptions{nullptr}};

to

#include <windows.h>

std::wstring stringToWString(const std::string& str) {
    if (str.empty()) return std::wstring();

    int sizeNeeded = MultiByteToWideChar(CP_UTF8, 0, &str[0], (int)str.size(), NULL, 0);
    std::wstring wstrTo(sizeNeeded, 0);
    MultiByteToWideChar(CP_UTF8, 0, &str[0], (int)str.size(), &wstrTo[0], sizeNeeded);
    return wstrTo;
}
Ort::Session session_{env, stringToWString(k_feature_model_path).c_str(), Ort::SessionOptions{nullptr}};
