tf.raw_ops.FusedResizeAndPadConv2D(
    input, size, paddings, filter, mode, strides, padding,
    resize_align_corners=False, name=None
)

It's often possible to do spatial transformations more efficiently as part of the packing stage of a convolution, so this op allows for an optimized implementation where these stages are fused together. This prevents the need to write out the intermediate results as whole tensors, reducing memory pressure, and we can get some latency gains by merging the transformation calculations. The data_format attribute for Conv2D isn't supported by this op, and defaults to 'NHWC' order. Internally this op uses a single per-graph scratch buffer, which means that it will block if multiple versions are being run in parallel. This is because this operator is primarily an optimization to minimize memory usage.

Args
input	A Tensor. Must be one of the following types: half, float32, float64. 4-D with shape [batch, in_height, in_width, in_channels].
size	A Tensor of type int32. A 1-D int32 Tensor of 2 elements: new_height, new_width. The new size for the images.
paddings	A Tensor of type int32. A two-column matrix specifying the padding sizes. The number of rows must be the same as the rank of input.
filter	A Tensor. Must have the same type as input. 4-D with shape [filter_height, filter_width, in_channels, out_channels].
mode	A string from: "REFLECT", "SYMMETRIC".
strides	A list of ints. 1-D of length 4. The stride of the sliding window for each dimension of input. Must be in the same order as the dimension specified with format.
padding	A string from: "SAME", "VALID". The type of padding algorithm to use.
resize_align_corners	An optional bool. Defaults to False. If true, the centers of the 4 corner pixels of the input and output tensors are aligned, preserving the values at the corner pixels. Defaults to false.
name	A name for the operation (optional).

Returns
A Tensor. Has the same type as input.
