coco issue

[bughunter99]

Hi,

I tried to run the code on my pc that has python 3.6.
But because of below issue, it couldn't run.

from pycocotools.coco import COCO
ModuleNotFoundError: No module named 'pycocotools'

And I found it is impossible to use pycoco on python 3.x in below.

Is retinanet only possible to run on python 2.x?
Thanks.

keras-retinanet should work fine on both python2 and python3. Did you follow the README? It explains how to install pycocotools. If this doesn't work for you, can you share the error you get when trying to install pycocotools?

Thanks. I had tried to do it on windows.
And I found pycocotools could not support windows for some reasons.

cocodataset/cocoapi#51

I'll give up ^^;

Ah I see. You can try to use PascalVOC instead, or make your own CSV dataset (or install a real OS ;p).

I'll close this issue then.

Ok, I checked PascalVOC runned on my pc. Thanks.

hi @bughunter99 You can replace extra_compile_args=['-Wno-cpp', '-Wno-unused-function', '-std=c99'] with extra_compile_args={'gcc': ['/Qstd=c99']} in ./libs/datasets/pycocotools/setup.py. maybe help

To anyone else that stumbles on this, by installing Visual Studio 2017 with C++ support and then following Chunde's suggestion I was able to get the cocoapi to install properly on Windows 10. Thanks for the suggestion Chunde!
