seq = tensorflow.keras.layers.LayerNormalization(tensorflow.keras.layers.Add([seq1,seq])) TypeError: __init__() takes 1 positional argument but 2 were given

这个错误提示表明 LayerNormalization 的初始化函数只接受一个位置参数，但是你传递了两个参数。可能的原因是 `tensorflow.keras.layers.Add([seq1,seq])` 返回的是一个列表，而 LayerNormalization 期望的是一个张量。你需要将这个列表中的张量相加，然后再传递给 LayerNormalization。可以尝试以下代码：

add = tensorflow.keras.layers.Add()([seq1, seq])
seq = tensorflow.keras.layers.LayerNormalization()(add)

这里我们首先定义了一个 `tensorflow.keras.layers.Add()` 层，然后将两个张量作为列表传递给它，得到它们的和。接着我们将这个和张量传递给 `tensorflow.keras.layers.LayerNormalization()` 层，并执行标准化操作。

losses = tensorflow.leagcy_seq2seq.sequence_loss_by_example

抱歉，你的代码中存在一些错误。正确的函数名称是 `tf.contrib.legacy_seq2seq.sequence_loss_by_example` 而不是 `tensorflow.leagcy_seq2seq.sequence_loss_by_example`。此外，`tf.contrib` 模块已经被废弃，建议使用新的模块 `tf.compat.v1`。因此，正确的代码应该是这样的：

import tensorflow as tf

# Define your logits and targets

losses = tf.compat.v1.nn.seq2seq.sequence_loss_by_example(
    logits=[logits],
    targets=[targets],
    weights=[weights]
)

# Compute the average loss
cost = tf.reduce_mean(losses)

请注意，你需要将 `logits`、`targets` 和 `weights` 替换为你实际使用的张量。

下面代码在tensorflow中出现了init() missing 1 required positional argument: 'cell'报错： 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= 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) def build_discriminator(self): def d_layer(layer_input, filters, f_size=4, bn=True): d = tf.keras.layers.Conv2D(filters, kernel_size=f_size, strides=2, padding='same')(layer_input) if bn: d = tf.keras.layers.BatchNormalization(momentum=0.8)(d) d = tf.keras.layers.LeakyReLU(alpha=0.2)(d) return d img_A = tf.keras.layers.Input(shape=(10, 128, 128, 3)) img_B = tf.keras.layers.Input(shape=(128, 128, 3)) df = 32 lstm_out = ConvRNN2D(filters=df, kernel_size=4, padding="same")(img_A) lstm_out = tf.keras.layers.LeakyReLU(alpha=0.2)(lstm_out) combined_imgs = tf.keras.layers.Concatenate(axis=-1)([lstm_out, img_B]) d1 = d_layer(combined_imgs, df)#64 d2 = d_layer(d1, df * 2)#32 d3 = d_layer(d2, df * 4)#16 d4 = d_layer(d3, df * 8)#8 validity = tf.keras.layers.Conv2D(1, kernel_size=4, strides=1, padding='same')(d4) return tf.keras.Model([img_A, img_B], validity)

你在定义 Model 类时，没有传入参数 cell，但是在代码中使用了 ConvRNN2D 的实例化对象，这个对象需要一个 cell 参数。你需要在初始化函数中添加这个参数，如下所示：

    def __init__(self, cell):
        self.img_seq_shape=(10,128,128,3)
        self.img_shape=(128,128,3)

        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()
