Good job there Shreejal. I am unable to grasp the concept of "switchable atrous convolution", I have been stuck for a week now. I asked on StackOverflow but no response yet. Can you please elaborate more on this specific topic? Here is the link to my question on StackOverflow: https://stackoverflow.com/questions/65833638/what-is-switchable-atrous-convolution-and-why-we-use-it

Thank you.
