File "D:\23101\比赛\光电赛\maze_car\测试\11111.py", line 46, in dijkstra heapq.heappush(heap, (new_distance, neighbor)) TypeError: '<' not supported between instances of 'Node' and 'Node'错误如上代码如下 def dijkstra(self, start_node): start_node.distance = 0 heap = [(start_node.distance, start_node)] while heap: (distance, node) = heapq.heappop(heap) if node.visited: continue node.visited = True for (neighbor, edge_distance) in node.neighbors: if not neighbor.visited: new_distance = node.distance + edge_distance if new_distance < neighbor.distance: neighbor.distance = new_distance heapq.heappush(heap, (new_distance, neighbor))

这个错误是由于在使用 `heapq` 堆操作时，Python 不知道如何比较节点（`Node`）对象。您需要在 `Node` 类中实现 `__lt__` 方法，以便 Python 可以比较这些对象。

例如：

class Node:
    def __init__(self, id):
        self.id = id
        self.distance = float('inf')
    
    def __lt__(self, other):
        return self.distance < other.distance

在这个示例中，我们将 `Node` 类的 `distance` 属性用作比较对象。请根据您的实际需要修改此代码。
