Make sure you've followed the Tensorflow Object Detection API installation guide:

• https://github.com/tensorflow/models/blob/master/research/object_detection/g3doc/installation.md

To start inference using images in the test_images/ folder:

$ python3 detect_single_image.py 

The above do inference with a single image then save the image with boxes. Good example for docker use/test.

To start inferencing using multiple images in the test_images folder. Result images will pop up but you'll need access to X(which most docker doesn't have)

$ python3 detect_multiple_images.py 

To start inference using webcam(require access to webcam and X display:

$ python3 detect_webcam.py
