Performs max pooling on the input and outputs both max values and indices.
tf.compat.v1.nn.max_pool_with_argmax(
input, ksize, strides, padding, data_format='NHWC', Targmax=None,
name=None, output_dtype=None, include_batch_in_index=False
)
The indices in argmax
are flattened, so that a maximum value at position
[b, y, x, c]
becomes flattened index:
(y * width + x) * channels + c
if include_batch_in_index
is False;
((b * height + y) * width + x) * channels + c
if include_batch_in_index
is True.
The indices returned are always in [0, height) x [0, width)
before flattening,
even if padding is involved and the mathematically correct answer is outside
(either negative or too large). This is a bug, but fixing it is difficult to do
in a safe backwards compatible way, especially due to flattening.
