Args |
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", "EXPLICIT" .
The type of padding algorithm to use.
|
explicit_paddings
|
An optional list of ints . Defaults to [] .
|
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).
|
Returns |
A Tensor . Has the same type as input .
