## Public functions

### DataFormat

```
TF_MUST_USE_RESULT Attrs tensorflow::ops::Conv2D::Attrs::DataFormat(
  StringPiece x
)
```

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: \[batch, channels, height, width\].


Defaults to "NHWC"

### Dilations

```
TF_MUST_USE_RESULT Attrs tensorflow::ops::Conv2D::Attrs::Dilations(
  const gtl::ArraySlice< int > & x
)
```

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.


Defaults to \[1, 1, 1, 1\]

### ExplicitPaddings

```
TF_MUST_USE_RESULT Attrs tensorflow::ops::Conv2D::Attrs::ExplicitPaddings(
  const gtl::ArraySlice< int > & x
)
```

If
`
padding
`
is
`
"EXPLICIT"
`
, the list of explicit padding amounts.


For the ith dimension, the amount of padding inserted before and after the dimension is
`
explicit_paddings[2 * i]
`
and
`
explicit_paddings[2 * i + 1]
`
, respectively. If
`
padding
`
is not
`
"EXPLICIT"
`
,
`
explicit_paddings
`
must be empty.


Defaults to \[\]

### UseCudnnOnGpu

```
TF_MUST_USE_RESULT Attrs tensorflow::ops::Conv2D::Attrs::UseCudnnOnGpu(
  bool x
)
```

Defaults to true.
