Original cocoapi: https://github.com/cocodataset/cocoapi.git
To run julcocoDemo you need to first run "make" under cocoapiJulia/PythonAPI
I needed to change the pycocotools/coco.py file to fix some type errors between Julia and Python. You can find the changes commented around line 265.
If you want to run the pycocoDemo please revert those changes.
