Downsamples the input representation by taking the average value over the
window defined by `pool_size`. The window is shifted by `strides`.  The
resulting output when using "valid" padding option has a shape of:
`output_shape = (input_shape - pool_size + 1) / strides)`

The resulting output shape when using the "same" padding option is:
`output_shape = input_shape / strides`

For example, for strides=1 and padding="valid":

>>> x = tf.constant([1., 2., 3., 4., 5.])
>>> x = tf.reshape(x, [1, 5, 1])
>>> x
<tf.Tensor: shape=(1, 5, 1), dtype=float32, numpy=
  array([[[1.],
          [2.],
          [3.],
          [4.],
          [5.]], dtype=float32)>
>>> avg_pool_1d = tf.keras.layers.AveragePooling1D(pool_size=2,
...    strides=1, padding='valid')
>>> avg_pool_1d(x)
<tf.Tensor: shape=(1, 4, 1), dtype=float32, numpy=
array([[[1.5],
        [2.5],
        [3.5],
        [4.5]]], dtype=float32)>

For example, for strides=2 and padding="valid":

>>> x = tf.constant([1., 2., 3., 4., 5.])
>>> x = tf.reshape(x, [1, 5, 1])
>>> x
<tf.Tensor: shape=(1, 5, 1), dtype=float32, numpy=
  array([[[1.],
          [2.],
          [3.],
          [4.],
          [5.]], dtype=float32)>
>>> avg_pool_1d = tf.keras.layers.AveragePooling1D(pool_size=2,
...    strides=2, padding='valid')
>>> avg_pool_1d(x)
<tf.Tensor: shape=(1, 2, 1), dtype=float32, numpy=
array([[[1.5],
        [3.5]]], dtype=float32)>

For example, for strides=1 and padding="same":

>>> x = tf.constant([1., 2., 3., 4., 5.])
>>> x = tf.reshape(x, [1, 5, 1])
>>> x
<tf.Tensor: shape=(1, 5, 1), dtype=float32, numpy=
  array([[[1.],
          [2.],
          [3.],
          [4.],
          [5.]], dtype=float32)>
>>> avg_pool_1d = tf.keras.layers.AveragePooling1D(pool_size=2,
...    strides=1, padding='same')
>>> avg_pool_1d(x)
<tf.Tensor: shape=(1, 5, 1), dtype=float32, numpy=
array([[[1.5],
        [2.5],
        [3.5],
        [4.5],
        [5.]]], dtype=float32)>

Args:
  pool_size: Integer, size of the average pooling windows.
  strides: Integer, or None. Factor by which to downscale.
    E.g. 2 will halve the input.
    If None, it will default to `pool_size`.
  padding: One of `"valid"` or `"same"` (case-insensitive).
    `"valid"` means no padding. `"same"` results in padding evenly to
    the left/right or up/down of the input such that output has the same
    height/width dimension as the input.
  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, steps, features)` while `channels_first`
    corresponds to inputs with shape
    `(batch, features, steps)`.

Input shape:
  - If `data_format='channels_last'`:
    3D tensor with shape `(batch_size, steps, features)`.
  - If `data_format='channels_first'`:
    3D tensor with shape `(batch_size, features, steps)`.

Output shape:
  - If `data_format='channels_last'`:
    3D tensor with shape `(batch_size, downsampled_steps, features)`.
  - If `data_format='channels_first'`:
    3D tensor with shape `(batch_size, features, downsampled_steps)`.
