您可以在中间添加 Reshape() 层以使尺寸兼容.

You can add Reshape() layer in between to make dimensions compatible.

keras.layers.core.Reshape(dims)

将输出重塑为特定形状.

Reshape an output to a certain shape.

输入形状

任意，尽管输入形状中的所有尺寸都必须固定.将此层用作模型中的第一层时，请使用关键字参数 input_shape(整数元组，不包括样本轴).

Arbitrary, although all dimensions in the input shaped must be fixed. Use the keyword argument input_shape (tuple of integers, does not include the samples axis) when using this layer as the first layer in a model.

输出形状

(batch_size,) + dims

参数

dims:目标形状.整数元组，不包括样本维度(batch size).

dims: target shape. Tuple of integers, does not include the samples dimension (batch size).
