<br />

    tf.keras.layers.ZeroPadding2D(
        padding=(1, 1), data_format=None, **kwargs
    )

This layer can add rows and columns of zeros
at the top, bottom, left and right side of an image tensor.

| ## Arguments ||
|---|---|
| `padding` | Int, or tuple of 2 ints, or tuple of 2 tuples of 2 ints. <br /> - If int: the same symmetric padding is applied to height and width. - If tuple of 2 ints: interpreted as two different symmetric padding values for height and width: `(symmetric_height_pad, symmetric_width_pad)`. - If tuple of 2 tuples of 2 ints: interpreted as `((top_pad, bottom_pad), (left_pad, right_pad))` |
| `data_format` | A string, one of `channels_last` (default) or `channels_first`. The ordering of the dimensions in the inputs. `channels_last` corresponds to inputs with shape `(batch, height, width, channels)` while `channels_first` corresponds to inputs with shape `(batch, channels, height, width)`. It defaults to the `image_data_format` value found in your Keras config file at `~/.keras/keras.json`. If you never set it, then it will be "channels_last". |

#### Input shape:

4D tensor with shape:

- If `data_format` is `"channels_last"`: `(batch, rows, cols, channels)`
- If `data_format` is `"channels_first"`: `(batch, channels, rows, cols)`

#### Output shape:

4D tensor with shape:

- If `data_format` is `"channels_last"`: `(batch, padded_rows, padded_cols, channels)`
- If `data_format` is `"channels_first"`: `(batch, channels, padded_rows, padded_cols)`
