def conv2d(x, W)在TensorFlow2里面报错

在 TensorFlow 2.x 里， `tf.nn.conv2d` 已经被移动到 `tf.nn` 模块的子模块 `tf.nn.convolution` 中。所以，你需要使用 `tf.nn.convolution` 来替换 `tf.nn.conv2d`。以下是一个使用 `tf.nn.convolution` 的示例：

import tensorflow as tf

# 定义输入和卷积核
x = tf.random.normal([1, 10, 10, 3])
W = tf.random.normal([3, 3, 3, 16])

# 进行卷积运算
out = tf.nn.convolution(x, W, padding='SAME')

print(out.shape)

请注意，这里的 `padding` 参数与 `tf.nn.conv2d` 的使用方式相同。可以选择 `'SAME'` 或 `'VALID'`。

这个错误提示是因为在调用`build_discriminator`方法时，缺少了必要的参数`cell`。这表明您在`Model`类中定义了一个名为`build_discriminator`的方法，并且该方法需要一个名为`cell`的参数，但是在实例化`Model`对象时没有传递该参数。

您需要检查`build_discriminator`方法的定义，看看它是否确实需要`cell`参数，并且如果需要，您需要在实例化`Model`对象时传递该参数。

这个错误提示是因为在你的Model类中，`init`方法应该被写成`__init__`，而且你需要传入一个参数`cell`。同时，你也需要在这个类中初始化`self.cell`，否则会出现`AttributeError: 'Model' object has no attribute 'cell'`的错误。需要注意的是，你在`build_generator`和`build_discriminator`方法中定义了一个局部函数`res_net`和`d_layer`，但是没有在这些方法中调用它们，这可能会导致逻辑错误。下面是修改后的代码：
