Defined in tensorflow/python/keras/_impl/keras/backend.py.

2D convolution with separable filters.

Arguments:

  • x: input tensor
  • depthwise_kernel: convolution kernel for the depthwise convolution.
  • pointwise_kernel: kernel for the 1x1 convolution.
  • strides: strides tuple (length 2).
  • padding: string, "same" or "valid".
  • data_format: string, "channels_last" or "channels_first".
  • dilation_rate: tuple of integers, dilation rates for the separable convolution.

Returns:

Output tensor.

Raises:

  • ValueError: if data_format is neither channels_last or channels_first.
