super(Model, self).__init__()

The code line `super(Model, self).__init__()` is used in Python to call the constructor of the parent class (superclass) of the current class.
In other words, it initializes the parent class of the current class. This is useful when we want to extend a class and need to use the functionality of its parent class as well.
The `super()` function returns a temporary object of the superclass, which allows us to call its methods. Here, we are calling the `__init__()` method of the parent class by passing the current class and `self` as arguments.

举例调用下面的方法 : class MultiHeadAttention(tf.keras.layers.Layer): def __init__(self, d_model, num_heads): super(MultiHeadAttention, self).__init__() self.num_heads = num_heads self.d_model = d_model assert d_model % self.num_heads == 0 self.depth = d_model // self.num_heads self.query_dense = tf.keras.layers.Dense(units=d_model) self.key_dense = tf.keras.layers.Dense(units=d_model) self.value_dense = tf.keras.layers.Dense(units=d_model) self.dense = tf.keras.layers.Dense(units=d_model)
假设你已经定义了一个名为 `model` 的神经网络模型,其中包含了 `MultiHeadAttention` 层,你可以使用下面的方法来调用这个层:
```
import tensorflow as tf
# 定义模型
class MyModel(tf.keras.Model):
def __init__(self):
super(MyModel, self).__init__()
self.multi_head_attention = MultiHeadAttention(d_model=64, num_heads=8)
def call(self, inputs):
# 调用 MultiHeadAttention 层
x = self.multi_head_attention(inputs)
return x
# 初始化模型
model = MyModel()
# 输入数据
inputs = tf.random.normal(shape=(32, 10, 64))
# 调用模型
outputs = model(inputs)
# 输出结果
print(outputs.shape)
```
在上面的代码中,我们首先定义了一个名为 `MyModel` 的神经网络模型,并在其中实例化了一个 `MultiHeadAttention` 层。然后,我们创建了一个 `model` 对象,该对象是 `MyModel` 的实例。接着,我们使用 `tf.random.normal()` 方法生成了一个形状为 `(32, 10, 64)` 的张量作为输入数据,然后将其传递给模型的 `call()` 方法,得到了模型的输出结果。最后,我们打印出了输出结果的形状。
下面这段代码的作用是什么: def __init__(self, title): super().__init__() self.ui = Ui_Dialog() self.ui.setupUi(self) self.save_path = 'result' self.save_id = 0 if not os.path.exists(self.save_path): os.mkdir(self.save_path) self.now = None self.model = None self.video_count = None self._timer = None self.ui.textBrowser.setFontPointSize(18) self.ui.label.setText(title) self.ui.pushButton_Model.clicked.connect(self.select_model) self.ui.pushButton_Img.clicked.connect(self.select_image_file) self.ui.pushButton_ImgFolder.clicked.connect(self.select_folder_file) self.ui.pushButton_Video.clicked.connect(self.select_video_file) self.ui.pushButton_Camera.clicked.connect(self.select_camear) self.ui.pushButton_SavePath.clicked.connect(self.select_savepath) self.ui.pushButton_BegDet.clicked.connect(self.begin_detect) self.ui.pushButton_StopDet.clicked.connect(self.stop_detect) self.ui.pushButton_Exit.clicked.connect(self._exit) self.show()
这段代码的作用是初始化一个名为 "title" 的类,并且连接了多个按钮的点击事件,用于选择模型、选择文件、选择摄像头、选择保存路径等操作。同时创建了一个名为 "result" 的文件夹,用于存储检测结果。
