Error while exciting the eval.py on TF object detection API

Question

i'm trying to evaluate my model using this command:

python eval.py --logtostderr --pipeline_config_path=training/faster_rcnn_inception_v2_pets.config --checkpoint_dir=inference_graph --eval_dir=eval

and im getting this error

and I'm getting this error:

Hi there!

Python 3 renamed the unicode type to str, the old str type has been replaced by bytes.

Knowing this it makes sense that we're getting errors as parts of the TF Object Detection API are deprecated (written using Python 2.x)

See here for more explanation on how to upgrade the code to be compatible with Python 3.

I hope this helps!
