Following the TF tutorial on pet object detection :
Ran locally :
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 :

This solved the same issue for me:
pip3 install -U scikit-image
pip3 install -U cython
pip3 install "git+"
(and use pip instead of pip3 if you are using python 2.7)
Following command worked for me.
pip install pycocotools
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.
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
Then in the PythonAPI directory, install library:
cd PythonAPI
python setup.py build_ext install
For Windows the sure way to do this is:
- Install Visual C++ 2015 Build Tools from with default selection.
- pip install git+^&subdirectory=PythonAPI
- First open a command prompt and run
git clone
- Then move to this directory
cd coco/PythonAPI
- 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
- And then in the coco/PythonAPI directory, run
python setup.py install
Your problem should be solved
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
