我试着用tensorflow小波把它作为一个层。到目前为止一切都很好，问题是我的输入是信号序列，当我运行代码时，它给了我下面的错误1。当我搜索tensorflow-wavelets的代码时，我发现代码使用了填充，这是专门用于图像的，我不知道该怎么办。任何帮助或建议？此外，我尝试使用自定义层或自定义函数以避免使用tensorflow-wavelets，但它给了我错误2。有什么需要帮忙的吗？
错误1：

ValueError: Exception encountered when calling layer "db1" (type DWT).

in user code:

    File "C:\Users\maa\anaconda3\envs\py37\lib\site-packages\tensorflow_wavelets\Layers\DWT.py", line 52, in call  *
        inputs_pad = tf.pad(inputs, [[0, 0], [0, 0], [self.dec_len-1, self.dec_len-1], [0, 0]], self.border_padd)

    ValueError: Shape must be rank 4 but is rank 2 for '{{node db1/MirrorPad}} = MirrorPad[T=DT_FLOAT, Tpaddings=DT_INT32, mode="SYMMETRIC"](Placeholder, db1/MirrorPad/paddings)' with input shapes: [?,512], [4,2].

Call arguments received by layer "db1" (type DWT):

  • training=None
  • mask=None

错误2：

NotImplementedError: Exception encountered when calling layer "activation_3" (type Activation).

Cannot convert a symbolic tf.Tensor (Placeholder:0) to a numpy array. This error may indicate that you're trying to pass a Tensor to a NumPy call, which is not supported.
