[英]python - ValueError: Tensor Tensor("dense_2/Softmax:0", shape=(?, 43), dtype=float32) is not an element of this graph
[英]ValueError: Tensor Tensor("mrcnn_detection/Reshape_1:0", shape=(1, 100, 6), dtype=float32) is not an element of this graph
我試圖使用帶有燒瓶的 rcnn 檢測形狀。 但是得到了這個錯誤:Traceback(最近一次調用):文件“C:\\Users\\KushalM\\AppData\\Local\\Continuum\\anaconda3\\lib\\site-packages\\tensorflow_core\\python\\framework\\ops.py”,第3505行,在 as_graph_element 返回 self._as_graph_element_ocked(obj, allow_tensor, allow_operation) raise ValueError("Tensor %s 不是這個圖的一個元素。" % obj) ValueError: Tensor Tensor("mrcnn_detection/Reshape_1:0", shape=(1, 100, 6), dtype=float32) 不是該圖的元素。
這是我的代碼:
