  --- BEGIN ISSUE ---
  CenterCrop.compute_output_shape() does not consider the list compatibility
  When the input is a list of tensor, CenterCrop can correctly generate the output, while` CenterCrop.compute_output_shape()` will generate a wrong shape. Please refer to this [gist](https://colab.research.google.com/drive/1JLuEr0-dNCmawTb2dRX7kaSxOKGZ6Obv?usp=sharing).
  
  Interestingly, I found the test code in [center_crop_test.py, ](https://github.com/keras-team/keras/blob/master/keras/layers/preprocessing/center_crop_test.py#L178) has tested the list compatibility, while its `compute_output_shape` function missed it.

  9     """A preprocessing layer which crops images.
  10 
  11     This layers crops the central portion of the images to a target size. If an
  12     image is smaller than the target size, it will be resized and cropped
  13     so as to return the largest possible window in the image that matches
  14     the target aspect ratio.
  15 
  16     Input pixel values can be of any range (e.g. `[0., 1.)` or `[0, 255]`).
  17 
  18     Input shape:
  19         3D (unbatched) or 4D (batched) tensor with shape:
  20         `(..., height, width, channels)`, in `"channels_last"` format,
  21         or `(..., channels, height, width)`, in `"channels_first"` format.
  22 
  23     Output shape:
  24         3D (unbatched) or 4D (batched) tensor with shape:
  25         `(..., target_height, target_width, channels)`,
  26         or `(..., channels, target_height, target_width)`,
  27         in `"channels_first"` format.
  28 
  29     If the input height/width is even and the target height/width is odd (or
  30     inversely), the input image is left-padded by 1 pixel.
  31 
  32     **Note:** This layer is safe to use inside a `tf.data` pipeline
  33     (independently of which backend you're using).
  34 
  35     Args:
  36         height: Integer, the height of the output shape.
  37         width: Integer, the width of the output shape.
  38         data_format: string, either `"channels_last"` or `"channels_first"`.
  39             The ordering of the dimensions in the inputs. `"channels_last"`
  40             corresponds to inputs with shape `(batch, height, width, channels)`
  41             while `"channels_first"` corresponds to inputs with shape
  42             `(batch, channels, height, width)`. It defaults to the
  43             `image_data_format` value found in your Keras config file at
  44             `~/.keras/keras.json`. If you never set it, then it will be
