I'm new to machine learning and have started with a windows 8.1 pc having GeForce GTX 540M. I followed this tutorial to get started with the object detection models. I built my own dataset and tried to train it as per the tutorial but with "ssd_mobilenet_v1_coco_2017_11_17" model. But could not perform it successfully as i had troubles with the "train.py" file given in the tutorial.

So I googled and found that we have to use "model_main.py" to train the model. While trying to train using "model_main.py" I got this error:
"ImportModuleError: No module named 'pycocotools' was found"

So I tried to install the cocoapi from this link . I followed the instructions as given, but got stuck with the error shown below, I've tried a lot of solutions but nothing worked. Any help will be much appreciated.

easy fix, use pip install pycocotools-windows

you can try:

pip install pycocotools-windows

it's worked for me :) on windows station :

I was getting the same error

 ValueError: 'pycocotools/_mask.pyx' doesn't match any files

So I cloned https://github.com/waleedka/coco to my local device. Then when I was running make I was getting the above error. the exact command I was running was--

C:\Users\Admin\Desktop\coco-master>python3 PythonAPI/setup.py build_ext install

I was when I was running above command I got the problem. Then I found out a solution on the issues page of the same repository. It happens that you have to cd into PythonAPI then run--

python setup.py build_ext --inplace

That solved some problems for me. Moreover some people were saying they still got problems but when they used python3 instead of python their problem was solved.

If you are getting this ERROR: Command errored out with exit status 1 or 2

Then install this:

pip install git+https://github.com/philferriere/cocoapi.git#egg=pycocotools^subdirectory=PythonAPI

pip install pycocotools-windows worked for me
