Tensorflow object detection evaluation pycocotools missing

Question

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 ?

Answer 1

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)

Answer 2

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.

Answer 3

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.

Answer 4

Following command worked for me.

pip install pycocotools
