I just solves this problem myself but it required changing their source files. Essentially your COCO dataset already has encoded RLEs which is what icevision convert all polygons and RLEs...
I wrote a pull request for this issue. https://github.com/airctic/icevision/pull/1166 It may also be worth the effort to write some COCOParser test cases for the various formats COCODatasets can take on.
Did you ever resolve this issue?
