Same problem too.

Traceback (most recent call last):

Installation of cocoapi is covered in https://github.com/tensorflow/models/blob/master/research/object_detection/g3doc/installation.md

I'm going to close this issue. If you followed these instructions and are still having issues feel free to reopen and @ me.

Hi @robieta, I think the confusion arises because in the Installation.md, it says

Download the cocoapi and copy the pycocotools subfolder to the tensorflow/models/research directory _if you are interested in using COCO evaluation metrics_

which gave me the impression that if I don't need to use the COCO evaluation metrics then I don't need to install it, resulting in this import error when I run the evaluation script. Possible to modify the wording there to make it sound compulsory?

[robieta]

That seems reasonable.

[mirayyuce]

It is still there, and still confusing. I got the same error for my custom dataset

[osvadimos]

The way I've solved it (and the way I solve all similar ones) :
git clone [email protected]:cocodataset/cocoapi.git
make # might be not necessary
python setup.py build
python setup.py install

All above when you've activated you virtual environment. Or will be installed globally at your wish.
