xception_block(inchannels, outchannels, nrepeats; stride = 1, start_with_relu = true, 
                    grow_at_start = true)

Create an Xception block. (reference)

Arguments

• inchannels: The number of channels in the input. The default value is 3.
• outchannels: number of output channels.
• nrepeats: number of repeats of depthwise separable convolution layers.
• stride: stride by which to downsample the input.
• start_with_relu: if true, start the block with a ReLU activation.
• grow_at_start: if true, increase the number of channels at the first convolution.
