[Keras] writes a custom network layer (layer) using Keras _deeplearning

Keras provides many common, prepared layer objects, such as the common convolution layer, the pool layer, and so on, which we can call directly through the following code: # Call a conv2d layer from Keras import layers conv2d = Keras.layers.convolutional.Conv2D (filters,\ kernel_size , \ strides= (1, 1), \ padding= ' valid ', \ ...) However, in practical applications, we often need to build some layer obje
