Object Detection API with TF2 AtributeError: module 'tensorflow' has no attribute 'contrib' from object_detection.builders import model_builder

[grewe]

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.
• [ x] I am reporting the issue to the correct repository. (Model Garden official or research directory)
• [ x] I checked to make sure that this issue has not already been filed.

1. The entire URL of the file you are using

https://github.com/tensorflow/models/tree/master/research/...

2. Describe the bug

When trying to import model_builder using following line in my jupyter notebook: from object_detection.builders import model_builder

get the following error TF2 AtributeError: module 'tensorflow' has no attribute 'contrib'

Have searched and past discussion is this is error is due to Object Detection being attempted to run with TF2 instead of TF1 but, 10 days ago Object Detection API released in TF2.

3. Steps to reproduce

Steps to reproduce the behavior. Have Jupyter notebook, running tensorflow 2.3 have line of code specified above to import model_builder and fails as discussed

4. Expected behavior

Expect no error.

5. Additional context

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

6. System information

• OS Platform and Distribution (e.g., Linux Ubuntu 16.04): Windows running Jupyter notebook in a conda environment
• Mobile device name if the issue happens on a mobile device:
• TensorFlow installed from (source or binary): (pip install)
• TensorFlow version (use command below): 2.3.0-rc2
• Python version: 3.7.4
• Bazel version (if compiling from source):
• GCC/Compiler version (if compiling from source):
• CUDA/cuDNN version:
• GPU model and memory:

Do you happen to know which line is trying to reference tf.contrib?

Have you made sure that the slim folder is on your python path? e,g,

export PYTHONPATH=$PYTHONPATH:/home/ubuntu/models/:/home/ubuntu/models/research/:/home/ubuntu/models/research/slim/://home/ubuntu/lugs/models/research/object_detection/

Have you solved it? I have the same problem. I hope to get your help. @greweI

[TadaasCirk]

Hi, I have the exact same problem. Anyone managed to solve this?

[theodorhar]

I had the same issue when using an anaconda environment 3.7.4 also with the pip distribution of tf_object_detection. I was able to get the object-detection API to work by fixing the dependencies, which for me meant scrapping the conda env and remaking it via this tutorial: https://tensorflow-object-detection-api-tutorial.readthedocs.io/en/latest/install.html

[masspern]

Same issue here. Is "use TF 1.x" the only solution at the moment?? Thx
