ImportError

[Jeff-sjtu]

Hi,
When I run COCOanalyze_demo.ipynb in jupyter notebook, there is an Import Error

---------------------------------------------------------------------------
ImportError                               Traceback (most recent call last)

      7 from pycocotools.cocoeval import COCOeval
      8 from pycocotools.cocoanalyze import COCOanalyze

ImportError: No module named _mask

Hi, this error occurs because you are not able to import the module _mask from the standard coco API (from pycocotools.coco import COCO), not when you import COCOanalyze.

Make sure you follow the instructions on their github page, and install the cocoAPi correctly, after that my code will work without any addition needed.

In particular, have you run the command python setup.py build_ext --inplace, as indicated here?
