Integrate a non local block with Mask R-CNN?

[Sudharshan Chandra Babu]

Hi, the original paper tested a Mask R-CNN with a non-local block (by adding one non-local block
right before the last residual block of res4 ).

I want to use your non-local block for object detection along with Mask R-CNN ( say https://github.com/matterport/Mask_RCNN )

How do I go about this?
