clang: error: no such file or directory: 'pycocotools/_mask.c' when running the makefile

[Mangouste]

I am trying to install coco locally. Yet it seems some files are missing when running the makefile, it seems it cannot find the pycocotools/_mask.c file. This file appears to be missing or not properly generated.

There was no need to rebuild the file as the MakeFile already has python setup.py build_ext --inplace

It might be helpful to try installing pycocotools directly from the GitHub repository, "git+https://github.com/philferriere/cocoapi.git#egg=pycocotools&subdirectory=PythonAPI"

pip install cython did the trick for me
