I've followed the readme instructions to install the require packages. Coco is not installed as part of requirements.txt.
When I run the demo.ipynb I get the following error message:
ImportError Traceback (most recent call last)

ImportError: No module named 'pycocotools'
I then followed the build instructions for coco from here:
https://github.com/cocodataset/cocoapi/tree/master/PythonAPI
But I modified the makefile to build it for Pyhon3. This appeared to work as I didn't get any build issues.
make install
This produces the following output:

It appears to build and install correctly. If I open up ipython3 and import coco I get the same error.

I found coco.py in samples/coco. For some reason the Jupyter notebook wasn't picking it up, so I just copied and pasted each line into ipython3 based on this notebook:
https://github.com/matterport/Mask_RCNN/blob/master/samples/demo.ipynb
I get the following results:
