Hi Team, I’m trying to run this “model_main_tf2.py” from this link

I’m getting this attribute error.

@Leelaram_Jayaram,

Can you try to import the model_lib_v2 from the object_detection module as shown in source code ?

Thank you!

@chunduriv thanks a lot for responding, I was able to import the module. Now I’m currently getting this error.

I’m able to see this CocoKeypointEvaluator class in coco_evalution.py file in my local. I’m not sure why I’m getting this error. Can you please share your thoughts.

Issue resolved by setting the right environment variables for PATH and PYTHONPATH.

could you please clarify more what exactly was the solution

I made a mistake of not adding models/research, models/research/slim, models/research/object_detection in system path, as a result I was getting this errors, when I did the same it got resolved. same with PYTHON_PATH as well.
