AffordanceNet architecture implementation

[apicis]

Hi, I have few questions about the network implementation:

• Did you start from an available Mask R-CNN implementation for AffordanceNet? Or did you compose the network connecting and VGG, RPN, and modifying the head?
• Was the initial model pretrained on COCO or some other dataset?
• The note in the README.md states that the available architecture is slightly different from the paper. Could you please list these differences?

Thank you very much
