我有一個C++函數,它返回vector<vector<double> >
對象。我已經使用Swig將它包裝爲Python。當我打電話時,我無法使用resize()
或push_back()
矢量方法修改函數的輸出。Python swig-wrapped矢量雙精度矢量顯示爲Tuple
當我嘗試這個時,我得到'元組'對象沒有'resize'或'push_back'屬性的錯誤。當我在Python中與它們交互時,Swig是否會將矢量轉換爲Tuple對象?如果是這樣的話,那麼我假設Python中這個函數的輸出是不可變的,這是一個問題。我可以將這個對象傳遞給接受一個雙向量向量的包裝方法。我不能用Python中的矢量方法搞砸它。爲什麼這是或解決辦法的任何解釋將不勝感激。
這是我的swig文件以供參考。 STL模板行接近尾聲:
