|
6 | * Depthwise 2D convolution.
|
7 | *
|
8 | * Given a 4D `input` array and a `filter` array of shape
|
9 | * `[filterHeight, filterWidth, inChannels, channelMultiplier]` containing
|
10 | * `inChannels` convolutional filters of depth 1, this op applies a
|
11 | * different filter to each input channel (expanding from 1 channel to
|
12 | * `channelMultiplier` channels for each), then concatenates the results
|
13 | * together. The output has `inChannels * channelMultiplier` channels.
|
14 | *
|
15 | * See
|
16 | * [https://www.tensorflow.org/api_docs/python/tf/nn/depthwise_conv2d](

17 | * https://www.tensorflow.org/api_docs/python/tf/nn/depthwise_conv2d)
|
18 | * for more details.
|
19 | *
|
20 | * @param x The input tensor, of rank 4 or rank 3, of shape
|
21 | * `[batch, height, width, inChannels]`. If rank 3, batch of 1 is
|
22 | * assumed.
|
23 | * @param filter The filter tensor, rank 4, of shape
|
24 | * `[filterHeight, filterWidth, inChannels, channelMultiplier]`.
|
25 | * @param strides The strides of the convolution: `[strideHeight,
|
26 | * strideWidth]`. If strides is a single number, then `strideHeight ==
|
27 | * strideWidth`.
|
28 | * @param pad The type of padding algorithm.
|
29 | * - `same` and stride 1: output will be of same size as input,
|
30 | * regardless of filter size.
|
31 | * - `valid`: output will be smaller than input if filter is larger
|
32 | * than 1x1.

|
35 | * https://www.tensorflow.org/api_docs/python/tf/nn/convolution)
|
36 | * @param dilations The dilation rates: `[dilationHeight, dilationWidth]`
|
37 | * in which we sample input values across the height and width dimensions
|
38 | * in atrous convolution. Defaults to `[1, 1]`. If `rate` is a single
|
39 | * number, then `dilationHeight == dilationWidth`. If it is greater than
|
40 | * 1, then all values of `strides` must be 1.
|
41 | * @param dataFormat: An optional string from: "NHWC", "NCHW". Defaults to
|
42 | * "NHWC". Specify the data format of the input and output data. With the
|
43 | * default format "NHWC", the data is stored in the order of: [batch,
|
44 | * height, width, channels]. Only "NHWC" is currently supported.
|
45 | * @param dimRoundingMode A string from: 'ceil', 'round', 'floor'. If none is
|
46 | * provided, it will default to truncate.
