def testModel(self, args, logfldr): log.debug("Test Model:") with open(logfldr + '/keyps_feature.json', 'r+') as t: data_keyps = json.load(t) with open("truth_data.json", "r+") as f: truth_keyps = json.load(f, object_pairs_hook=collections.OrderedDict)

这段代码的作用是测试模型。具体来说，它读取了一个名为`keyps_feature.json`的JSON文件，该文件包含了一些数据，然后将这些数据加载到`data_keyps`变量中。接着，它还读取了一个名为`truth_data.json`的JSON文件，该文件包含了一些标签数据，然后将这些标签数据加载到`truth_keyps`变量中。

AttributeError: 'Train' object has no attribute 'resnet50'

这个错误是由于在加载模型时出现了属性错误。根据引用\[1\]中的描述，可能是因为在保存模型时没有保存完整的模型参数。你可以尝试重新训练模型，并确保在保存模型时使用了正确的方法。另外，你还可以检查一下模型的定义和加载过程中是否有任何错误。

另外，根据引用\[2\]中的描述，你还需要确保在使用SummaryWriter.add_graph()之前将网络模型移动到正确的设备上。你可以使用torch.device()函数将模型移动到可用的GPU上，或者使用'cpu'参数将模型移动到CPU上。

最后，根据引用\[3\]中的描述，如果你的服务器只有两个GPU，并且你使用了两个GPU进行训练，那么在新服务器上可能会出现没有可用的CUDA设备的错误。你可以尝试使用只有一个GPU的服务器或者调整你的代码以适应新服务器的GPU数量。

综上所述，你可以尝试重新训练模型并保存完整的模型参数，确保将模型移动到正确的设备上，并根据服务器的GPU数量进行相应的调整，以解决这个错误。

帮我根据以下要求：Add to the Model class a new method called savaData that saves into a text file called "points.txt" the integer coordinates x and y of each point in the arraylist of points. Also modify the constructor of the Model class to read the integer coordinates of all the points from the same text file, if it exists, and put them into the arraylist of points (if the file does not exist then the arraylist of points should remain empty).public class Model { private ArrayList<Point> points; private ArrayList<ModelListener> listeners; public Model() { points = new ArrayList<Point>(); listeners = new ArrayList<ModelListener>(); } public void addListener(ModelListener l) { listeners.add(l); } public ArrayList<Point> getPoints() { return points; } public void addPoint(Point p) { points.add(p); notifyListeners(); // points changed so notify the listeners. } public void clearAllPoints() { points.clear(); notifyListeners(); // points changed so notify the listeners. } public void deleteLastPoint() { if(points.size() > 0) { points.remove(points.size() - 1); notifyListeners(); // points changed so notify the listeners. } } private void notifyListeners() { for(ModelListener l: listeners) { l.update(); // Tell the listener that something changed. } } public int numberOfPoints() { return points.size(); } public static void testModel() { Model m = new Model(); m.addListener(new ModelListener() { @Override public void update() { System.out.println(true + " (listener)"); } }); System.out.println(m.getPoints() == m.points); Point p1 = new Point(1, 2); Point p2 = new Point(3, 4); m.addPoint(p1); // Listener called. m.addPoint(p2); // Listener called.
