Tensorflow object detection evaluation pycocotools missing

Following the TF tutorial on pet object detection : https://github.com/tensorflow/models/blob/master/research/object_detection/g3doc/running_pets.md

Ran locally : https://github.com/tensorflow/models/blob/master/research/object_detection/g3doc/running_locally.md

The training seems to work well.

Trying to launch the evaluation process from the tensorflow/models/research/ directory

python object_detection/eval.py \
    --logtostderr \
    --pipeline_config_path=${PATH_TO_YOUR_PIPELINE_CONFIG} \
    --checkpoint_dir=${PATH_TO_TRAIN_DIR} \
    --eval_dir=${PATH_TO_EVAL_DIR}

I got the following error

from pycocotools import coco \
ModuleNotFoundError: No module named 'pycocotools'

Had a look on coco API but I don't see any clear way to install it on Windows.

Any advice on how to get the evaluation running the simpliest way ?

More details about the error message :

Traceback (most recent call last):   File "object_detection/eval.py", line 50, in <module>

Did you try pip install git+https://github.com/philferriere/cocoapi.git#egg=pycocotools^&subdirectory=PythonAPI (from github.com/matterport/Mask_RCNN/issues/6)? – Akshay Agrawal
Nope, will try ^^ – Frédéric Coubard
Some progress... Got an error about the & character : Le caractère perluète n’est pas autorisé. L’opérateur & est réservé à une utilisation future. Placez un caractère perluète entre guillemets doubles ("&") pour que ce symbole soit considéré comme une chaîne. + CategoryInfo : ParserError: (:) [], ParentContainsErrorRecordException + FullyQualifiedErrorId : AmpersandNotAllowed So I added quote... Cloning working but stopped because Microsoft Visual C++ 14.0 required. Will see If I can add it. – Frédéric Coubard
Did you try pip install pycocotools? – tsveti_iko

This solved the same issue for me:

pip3 install -U scikit-image
pip3 install -U cython 
pip3 install "git+https://github.com/philferriere/cocoapi.git#egg=pycocotools&subdirectory=PythonAPI"

(and use pip instead of pip3 if you are using python 2.7)

Could you post the full stack trace so we can see where pycocotools is being imported from? We're adding COCO support to the Tensorflow Object-Detection API (with a few other goodies), and will update the installation instructions soon.

I had the same problem and solved it, but unfortunately for you, I am working on Ubuntu. But hopefully this helps someone else with the same issue:

First of all, you need to follow the steps that are described in the install guide of the object detection api. In my case though, that was not enough, I had the same problem as before. During the installation process described there, you download a github repository, specifically this one.

What I did next was to navigate to the folder cocoapi/PythonAPI and running 

sudo python3 setup.py install

Evaluation script seems to be working now.

This worked for me:

git clone https://github.com/cocodataset/cocoapi

Then in the PythonAPI directory, install library:

cd PythonAPI
python setup.py build_ext install

For Windows the sure way to do this is:

  1. Install Visual C++ 2015 Build Tools from https://go.microsoft.com/fwlink/?LinkId=691126 with default selection.
  2. pip install git+https://github.com/philferriere/cocoapi.git#egg=pycocotools^&subdirectory=PythonAPI

  1. First open a command prompt and run
git clone https://github.com/pdollar/coco.git
  1. Then move to this directory
cd coco/PythonAPI
  1. And then edit the setup.py file in the coco/PythonAPI directory from this 
extra_compile_args=['-Wno-cpp', '-Wno-unused-function', '-std=c99'],

to this

extra_compile_args=['-std=c99'],

then save

  1. And then in the coco/PythonAPI directory, run
python setup.py install

Your problem should be solved

Following command worked for me.

The best and the easiest way to fix this error is to just use pip to install it

!pip install -q pycocotools

You can use pip3 if you have python3 and you are in Linux or mac

It works for me with this just simple method. If you are windows, try to install pycocotools in windows version. With code in following:

pip install pycocotools-windows

With this method, you don't need to install any visual build tools. Hope this can help those who finding the ways of installing pycocotools.
