我喜欢快速、紧凑的代码，所以我有一个问题：

def loader(input_path, new_img_width, new_img_height):
    input_image = tifffile.imread(input_path)
    input_image = cv2.resize(input_image, (new_img_width, new_img_height),
                           interpolation=cv2.INTER_NEAREST)
    return input_image

我是否需要在调用之前添加条件语句cv2.resize，以处理其中new_img_width和new_img_height相同的情况input_image或cv2.resize代码中已经存在的条件语句？

除非有必要，否则我不想花费周期调整图像大小。

当我使用simple_save保存模型时，尝试加载模型时出现运行时错误。

要保存的代码是：

session = Session()
inputs = tf.placeholder(dtype=tf.float32, shape=(None, height, width, in_channel_size), name='input_img')
model = Some_Model(inputs, num_classes=no_of_defects, is_training=False)
logits, _ = model.build_model()
predictor = tf.nn.softmax(self.logits, name='logits_to_softmax')
feed_dict = {inputs: inputs}
prediction_probabilities = session.run(self.predictor, feed_dict=feed_dict)

tf.saved_model.simple_save(self.session, path,
                               inputs={"inputs" : self.inputs},
                               outputs={"predictor": self.predictor})

要加载的代码是：

tf.saved_model.loader.load(session, tag_constants.SERVING, path)

给出错误：

RuntimeError: MetaGraphDef associated with tags serve could not be found in SavedModel. To inspect available tag-sets in the SavedModel, please use the SavedModel CLI: `saved_model_cli`

当我跑步

saved_model_cli show --dir path --tag_set serve --signature_def serving_default …

我已经尝试通过snap和apt-get安装VS Code

在这两种情况下code，我都无法在使用VNC访问xfce GUI的Ubuntu 16.04服务器上运行。当我code --verbose从终端窗口运行时，我得到

我正在使用.NET 4.5.1运行C#控制台应用程序.当我运行以下函数时,下面的udpClient.ReceiveAsync()调用默默地终止程序,没有异常.我该如何调试？

   public async void Run()
    {
        try
        {
            var armIpAddress = IPAddress.Parse("239.1.11.1");
            using (var udpClient = new UdpClient())
            {
                udpClient.ExclusiveAddressUse = false;
                var ipEndPoint = new IPEndPoint(IPAddress.Any, 12020);
                udpClient.Client.SetSocketOption(SocketOptionLevel.Socket, SocketOptionName.ReuseAddress, true);
                udpClient.ExclusiveAddressUse = false;
                udpClient.Client.Bind(ipEndPoint);
                udpClient.JoinMulticastGroup(armIpAddress);

                while (true)
                {
                    var result = await udpClient.ReceiveAsync();
                    //...
                }
        }
        catch (Exception x)
        {
            Console.WriteLine(x.Message);
        }
    }
