将下面代码使用ConvRNN2D层来替换ConvLSTM2D层，并在模块__init__.py中创建类‘convrnn’ class Model(): def __init__(self): self.img_seq_shape=(10,128,128,3) self.img_shape=(128,128,3) self.train_img=dataset # self.test_img=dataset_T patch = int(128 / 2 ** 4) self.disc_patch = (patch, patch, 1) self.optimizer=tf.keras.optimizers.Adam(learning_rate=0.001) self.build_generator=self.build_generator() self.build_discriminator=self.build_discriminator() self.build_discriminator.compile(loss='binary_crossentropy', optimizer=self.optimizer, metrics=['accuracy']) self.build_generator.compile(loss='binary_crossentropy', optimizer=self.optimizer) img_seq_A = Input(shape=(10,128,128,3)) #输入图片 img_B = Input(shape=self.img_shape) #目标图片 fake_B = self.build_generator(img_seq_A) #生成的伪目标图片 self.build_discriminator.trainable = False valid = self.build_discriminator([img_seq_A, fake_B]) self.combined = tf.keras.models.Model([img_seq_A, img_B], [valid, fake_B]) self.combined.compile(loss=['binary_crossentropy', 'mse'], loss_weights=[1, 100], optimizer=self.optimizer,metrics=['accuracy']) def build_generator(self): def res_net(inputs, filters): x = inputs net = conv2d(x, filters // 2, (1, 1), 1) net = conv2d(net, filters, (3, 3), 1) net = net + x # net=tf.keras.layers.LeakyReLU(0.2)(net) return net def conv2d(inputs, filters, kernel_size, strides): x = tf.keras.layers.Conv2D(filters, kernel_size, strides, 'same')(inputs) x = tf.keras.layers.BatchNormalization()(x) x = tf.keras.layers.LeakyReLU(alpha=0.2)(x) return x d0 = tf.keras.layers.Input(shape=(10, 128, 128, 3)) out= tf.keras.layers.ConvRNN2D(filters=32, kernel_size=3,padding='same')(d0) out=tf.keras.layers.Conv2D(3,1,1,'same')(out) return keras.Model(inputs=d0, outputs=out)

以下是使用ConvRNN2D层替换ConvLSTM2D层的修改后的代码：

from tensorflow.keras.layers import Conv2D, Conv2DTranspose, ConvRNN2D, Input, BatchNormalization, LeakyReLU, Flatten, Dense, Reshape
from tensorflow.keras.models import Model

        self.combined = Model([img_seq_A, img_B], [valid, fake_B])
        self.combined.compile(loss=['binary_crossentropy', 'mse'],
                              loss_weights=[1, 100],
                              optimizer=self.optimizer,

        def res_net(inputs, filters):
            x = inputs
            net = conv2d(x, filters // 2, (1, 1), 1)
            net = conv2d(net, filters, (3, 3), 1)
            net = net + x

            return net
        
        def conv2d(inputs, filters, kernel_size, strides):
            x = Conv2D(filters, kernel_size, strides, 'same')(inputs)
            x = BatchNormalization()(x)
            x = LeakyReLU(alpha=0.2)(x)
            return x
        
        d0 = Input(shape=(10, 128, 128, 3))
        out = ConvRNN2D(filters=32, kernel_size=3, padding='same')(d0)
        out = conv2d(out, 3, 1, 1)
        
        return Model(inputs=d0, outputs=out)
    
    def build_discriminator(self):
        def d_layer(layer_input, filters, f_size=4, normalization=True):
            """Discriminator layer"""
            d = Conv2D(filters, kernel_size=f_size, strides=2, padding='same')(layer_input)
            if normalization:
                d = BatchNormalization()(d)
            d = LeakyReLU(alpha=0.2)(d)
            return d
        
        img_A = Input(shape=self.img_seq_shape)
        img_B = Input(shape=self.img_shape)

        combined_imgs = tf.keras.layers.concatenate([img_A, img_B])

        d1 = d_layer(combined_imgs, 64, normalization=False)
        d2 = d_layer(d1, 128)
        d3 = d_layer(d2, 256)
        d4 = d_layer(d3, 512)

        validity = Conv2D(1, kernel_size=4, strides=1, padding='same')(d4)

        return Model([img_A, img_B], validity)

在代码中，我们将ConvLSTM2D层替换为了ConvRNN2D层，并添加了新的模块`convrnn`。
