Module tensorflow has no attribute contrib

Question

I am trying to train my own custom object detector using Tensorflow Object-Detection-API   I installed the tensorflow using  pip install tensorflow  in my google compute engine  Then I followed all the instructions on this site  https   tensorflow-object-detection-api-tutorial readthedocs io en latest training html   When I try to use train py I am getting this error message      Traceback  most recent call last     File  train py   line 49  in     from object detection builders import dataset builder   File   usr local lib python3 6 dist-packages object detection-0 1- py3 6 egg object detection builders dataset builder py   line 27  in    from object detection data decoders import tf example decoder   File   usr local lib python3 6 dist-packages object detection-0 1-py3 6 egg object detection data decoders tf example decoder py   line 27  in        slim example decoder   tf contrib slim tfexample decoder   AttributeError  module  tensorflow  has no attribute  contrib    Also I am getting different results when I try to learn version of tensorflow      python3 -c  import tensorflow as tf  print tf version     2 0 0-dev20190422   and when I use     pip3 show tensorflow        Name  tensorflow   Version  1 13 1   Summary  TensorFlow is an open source machine learning framework for everyone    Home-page  https   www tensorflow org    Author  Google Inc    Author-email  opensource google com   License  Apache 2 0   Location   usr local lib python3 6 dist-packages   Requires  gast  astor  absl-py  tensorflow-estimator  keras-preprocessing  grpcio  six  keras-applications  wheel  numpy  tensorboard  protobuf  termcolor   Required-by         sudo python3 train py --logtostderr --train dir training  --      pipeline config path training ssd inception v2 coco config   What should I do to solve this problem  I couldn t find anything about this error message except this  tensorflow   39 module  39  object has no attribute   39 contrib  39

I used google colab to run my models and everything was perfect untill i used inline tesorboard. With tensorboard inline, I had the same issue of "Module 'tensorflow' has no attribute 'contrib'".

It was able to run training when rebuild and reinstall the model using setup.py(research folder) after initialising tensorboard.

This issue might be helpful for you  it explains how to achieve TPUStrategy  a popular functionality of tf contrib in TF lt 2 0   So  in TF 1 X you could do the following   resolver   tf contrib cluster resolver TPUClusterResolver  grpc       os environ  COLAB TPU ADDR    tf contrib distribute initialize tpu system resolver  strategy   tf contrib distribute TPUStrategy resolver    And in TF 2 0  where tf contrib is deprecated  you achieve the same by   tf config experimental connect to host  grpc       os environ  COLAB TPU ADDR    resolver   tf distribute cluster resolver TPUClusterResolver  grpc       os environ  COLAB TPU ADDR    tf tpu experimental initialize tpu system resolver  strategy   tf distribute experimental TPUStrategy resolver

If you want to use tf contrib  you need to now copy and paste the source code from github into your script notebook  It s annoying and doesn t always work  But that s the only workaround I ve found  For example  if you wanted to use tf contrib opt AdamWOptimizer  you have to copy and paste from here  https   github com tensorflow tensorflow blob 590d6eef7e91a6a7392c8ffffb7b58f2e0c8bc6b tensorflow contrib opt python training weight decay optimizers py L32

I used tensorflow 1 8 to train my model and there is no problem for now  Tensorflow 2 0 alpha is not suitable with object detection API

tf contrib has moved out of TF starting TF 2 0 alpha  Take a look at these tf 2 0 release notes https   github com tensorflow tensorflow releases tag v2 0 0-alpha0 You can upgrade your TF 1 x code to TF 2 x using the tf upgrade v2 script https   www tensorflow org alpha guide upgrade
