I am sorry for asking this stupid question, I got this error, and I don't know why

python setup.py build_ext --inplace

I had built this a couple of days back.Just run make from the PythonAPI directory and it should fine.

I think there is a misleading typo in README:

For Python, run "make" under coco/PythonAPI...

It should be:

For Python, run "make" under coco/cocoapi/PythonAPI...

[lihua213]

@shenxiaolu1984 you are right. I just did it successfully!

[PardoAlejo]

@riokt I had the same problem, and Fixed it by installing cython. "pip install cython" and the make starts to work.

[wilderfield]

I had same problem as @PardoAlejo . make will not work unless Cython is installed, and this is not mentioned by the README

[pavanshahm]

I installed did "pip install Cython", however I'm still getting

clang: error: no such file or directory: 'pycocotools/_mask.c'
clang: error: no input files
error: command 'cc' failed with exit status 1

when I run make.

Am I still missing an intermediate step?
I already am within the PythonApi directory.

EDIT: Solved. I had. Cython for Python3, installing it for Python 2 did the trick.

[wilderfield]

cython should be lower case The error message looks like you didn't install cython

install Cython to solve this issue. if you use conda.
conda install Cython

and matplotlib is not mentioned by the README.
conda install matplotlib

[scylla]

for me using python3
pip install cython
then 'make' in coco/cocoapi/PythonAPI
followed by sudo python setup.py install solved the problem

[riokt]

This problem is already solved. The problem is in my Cython. But thank you for your help

[winnechan]

pip install cython cannot solve the issue TAT
can somebody help?

[oukohou]

@winnechan

maybe your pip -V is not python2?
if so, click "pip2 install cython" on your command line tool.

Hope helpful.

I had the same issue, but had cython installed for python3. I changed two lines in the Makefile to install for the non default python intrepreter:

all:
    # install pycocotools locally
        python3.6 setup.py build_ext --inplace
        rm -rf build

install:
        # install pycocotools to the Python site-packages
        python3.6 setup.py build_ext install
        rm -rf build
