A `Concatenate` layer requires inputs with matching shapes except for the concatenation axis. Received: input_shape=[(None, 32, 19, 512), (None, 32, 18, 512)]

这个错误提示是因为在使用 `Concatenate` 层时，输入的张量形状不匹配。具体来说，除了连接轴以外的维度应该是相同的。 根据你的错误提示，你正在尝试连接两个形状分别为 `(None, 32, 19, 512)` 和 `(None, 32, 18, 512)` 的张量，但它们的第三个维度不同。这意味着它们无法沿着第三个维度进行连接。 要解决这个问题，你可以通过调整模型中的某些层的形状来使它们匹配，或者使用 `Reshape` 层来显式调整张量的形状以使它们可以连接。例如，你可以使用 `Reshape` 层将 `(None, 32, 18, 512)` 的张量重塑为 `(None, 32, 19, 512)` 的形状，以便它们可以连接在一起： ```python from tensorflow.keras.layers import Concatenate, Reshape input1 = ... input2 = Reshape((32, 19, 512))(input2_resized) concatenated = Concatenate(axis=3)([input1, input2]) ``` 这里假设你已经将第二个输入张量调整为 `(None, 32, 19, 512)` 的形状。然后使用 `Concatenate` 层将两个张量沿着第四个维度连接起来。

A `Concatenate` layer requires inputs with matching shapes except for the concatenation axis. Received: input_shape=[(None, 5), (None, 5, 1)]

The `Concatenate` layer in Keras requires inputs with matching shapes along all axes except for the concatenation axis. In the received input shape [(None, 5), (None, 5, 1)], the first input has a shape of (None, 5) and the second input has a shape of (None, 5, 1). To resolve this issue and make the shapes compatible for concatenation, you can use a `Reshape` layer to reshape the second input from (None, 5, 1) to (None, 5). Here's an example: ```python from tensorflow.keras.layers import Concatenate, Reshape from tensorflow.keras.models import Model from tensorflow.keras.layers import Input input1 = Input(shape=(5,)) input2 = Input(shape=(5, 1)) reshaped_input2 = Reshape((5,), name='reshape')(input2) concatenated_output = Concatenate()([input1, reshaped_input2]) model = Model(inputs=[input1, input2], outputs=concatenated_output) ``` In this example, the `Reshape` layer is used to reshape the second input from (None, 5, 1) to (None, 5), and then the `Concatenate` layer is used to concatenate the reshaped input with the first input. Now the inputs have matching shapes along all axes, and you can proceed with your model.

Received: input_shape=[(None, 125, 100, 256), (None, 250, 200, 256)] 报错，解释

这是一个 Python 代码的错误信息。这个错误的原因是 `Concatenate` 层需要具有相同形状的输入，除了在拼接轴上。但是，你的代码中，`Concatenate` 层的输入形状不匹配。具体地说，你传递了两个张量给 `Concatenate` 层，但它们的大小不匹配。第一个输入的形状是 `(None, 125, 100, 256)`，而第二个输入的形状是 `(None, 250, 200, 256)`。因此，`Concatenate` 层无法将它们沿着轴 3 进行拼接。为了解决这个问题，你需要确保将两个输入张量的大小调整为相同的大小。
