Got an AttributeError: module 'tensorflow' has no attribute 'contrib' when following Tensorflow 2.0 object detection tutorial

Prerequisites

Please answer the following questions for yourself before submitting an issue.

• [X ] I am using the latest TensorFlow Model Garden release and TensorFlow 2.
• I am reporting the issue to the correct repository. (Model Garden official or research directory)
• I checked to make sure that this issue has not been filed already.

1. The entire URL of the file you are using

http://download.tensorflow.org/models/object_detection/tf2/20200711/faster_rcnn_resnet101_v1_640x640_coco17_tpu-8.tar.gz

2. Describe the bug

I am using tensorflow 2.0 and tried to follow the object detection tutorial (https://tensorflow-object-detection-api-tutorial.readthedocs.io/en/latest/auto_examples/object_detection_camera.html). However, when I tried to load the model, I got an Attribute error.

I did the research online and got the answer that you have to use tensorflow 1.4 to make the object detection work. and contrib has been deprecated in tensorflow 2.0.

I am confused that the tutorial for tensorflow 2.0 object detection api will require tensorflow 1.x??

3. Steps to reproduce

Use tensorflow 2.0, follow the TF 2.0 object detection tutorial, and when you load the model, you will get the issue.

4. Expected behavior

model get loaded correctly.

5. Additional context

Include any logs that would be helpful to diagnose the problem.
