Computes the gradients of depthwise convolution with respect to the filter.
tf.nn.depthwise_conv2d_backprop_filter(
input, filter_sizes, out_backprop, strides, padding, data_format='NHWC',
dilations=[1, 1, 1, 1], name=None
)
input
: A Tensor
. Must be one of the following types: half
, bfloat16
, float32
, float64
.
4-D with shape based on data_format
. For example, if
data_format
is 'NHWC' then input
is a 4-D [batch, in_height,
in_width, in_channels]
tensor.filter_sizes
: A Tensor
of type int32
.
An integer vector representing the tensor shape of filter
,
where filter
is a 4-D
[filter_height, filter_width, in_channels, depthwise_multiplier]
tensor.out_backprop
: A Tensor
. Must have the same type as input
.
4-D with shape based on data_format
.
For example, if data_format
is 'NHWC' then
out_backprop shape is [batch, out_height, out_width, out_channels]
.
Gradients w.r.t. the output of the convolution.strides
: A list of ints
.
The stride of the sliding window for each dimension of the input
of the convolution.padding
: A string
from: "SAME", "VALID"
.
The type of padding algorithm to use.data_format
: An optional string
from: "NHWC", "NCHW"
. Defaults to "NHWC"
.
Specify the data format of the input and output data. With the
default format "NHWC", the data is stored in the order of:
[batch, height, width, channels].
Alternatively, the format could be "NCHW", the data storage order of:
[batch, channels, height, width].dilations
: An optional list of ints
. Defaults to [1, 1, 1, 1]
.
1-D tensor of length 4. The dilation factor for each dimension of
input
. If set to k > 1, there will be k-1 skipped cells between each filter
element on that dimension. The dimension order is determined by the value of
data_format
, see above for details. Dilations in the batch and depth
dimensions must be 1.name
: A name for the operation (optional).A Tensor
. Has the same type as input
.
