kann nicht eingegeben werden Ich habe eine einfache Version bidirektionale lstm für die Satzklassifizierung geschrieben. Aber es gibt mir weiter "Sie müssen einen Wert für Platzhalter Tensor 'train_x'" -Fehler einspeisen und es scheint, dass dies aus dem Variableninitialisierungsschritt kommt.Wert für Platzhalter Tensor

und füttern Sie sie als zwei RNNClassifier() Argumente, aber es gibt immer noch den gleichen Fehler. Warum?
siehe Kommentare von @mrry zu diesem Beitrag http://stackoverflow.com/questions/34050071/tensorflow-random -shuffle-queue-is-closed-and-has-insufficient-Elemente. Es könnte helfen. –
Danke. Aber ich denke nicht, dass es das gleiche Problem ist. – Blue482
Bitte fügen Sie '' Gelöst ''nicht zu Ihrem Fragetitel hinzu. Wenn Sie eine Lösung haben, schreiben Sie unten eine Antwort. Ansonsten lass den Post einfach stehen. Stack Overflow ist kein * persönlicher * Fragenassistent. Fragen hier sollen auch zukünftigen Besuchern * hilfreich sein; Leute suchen nicht nach "aufgelösten" Markern, sie suchen, ob Sie das gleiche Problem haben und ob es eine Antwort gibt, die sie auch anwenden können. –
