tf.raw_ops.FusedPadConv2D

Performs a padding as a preprocess during a convolution.

tf.raw_ops.FusedPadConv2D(
    input, paddings, filter, mode, strides, padding, name=None
)

Similar to FusedResizeAndPadConv2d, this op allows for an optimized implementation where the spatial padding transformation stage is fused with the im2col lookup, but in this case without the bilinear filtering required for resizing. Fusing the padding 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 'NHWC' order is used instead. 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.

input A Tensor. Must be one of the following types: half, bfloat16, float32, float64. 4-D with shape [batch, in_height, in_width, in_channels].
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.
name A name for the operation (optional).

A Tensor. Has the same type as input.
