(

padding,
data_format='NHWC',
dilations=1,
name=None
)[source]¶Apply the 3d convolution.
- If
data_format
is'NCHW'
, excepts input shape \((N, C_{\text{in}}, D, H, W)\), filters shape \((C_{\text{out}}, C_{\text{in}}, D_{\text{f}}, H_{\text{f}}, W_{\text{f}})\), and output shape is \((N, C_{\text{out}}, D_{\text{out}}, H_{\text{out}}, W_{\text{out}})\). - If
data_format
is'NHWC'
, excepts input shape \((N, D, H, W, C_{\text{in}})\), filters shape \((C_{\text{out}}, D_{\text{f}}, H_{\text{f}}, W_{\text{f}}, C_{\text{in}})\), and output shape is \((N, D_{\text{out}}, H_{\text{out}}, W_{\text{out}}, C_{\text{out}})\). padding
could be'VALID'
,'SAME'
or explicit padding size.
Examples:
x = tf.ones((1, 2, 2, 2, 2)) filters = tf.ones((3, 1, 1, 1, 2)) y = tf.nn.conv3d(x, filters) assert y.shape == (1, 2, 2, 2, 3)
- Parameters:
- input (dragon.Tensor) – The input tensor.
- filters (dragon.Tensor) – The filters tensor.
- strides (Union[int, Sequence[int]], optional, default=1) – The stride of convolution window.
- padding (Union[int, Sequence[int], str], optional, default='VALID') – The padding algorithm or size.
- data_format (str, optional, default='NHWC') –
'NCHW'
or'NHWC'
. - dilations (Union[int, Sequence[int]], optional, default=1) – The rate of dilated filters.
- name (str, optional) – The operation name.
- Returns:
dragon.Tensor – The output tensor.
