AttributeError: module 'tensorflow' has no attribute 'contrib'

followed the instruction for installation but bumped into this error when running train.py

$ python3 train.py

I found some possible solutions here but couldn't figure it out..

Ok I tried this command:

tf_upgrade_v2 \
  --intree DeepLab-V3/ \
  --outtree DeepLab-V3_tf2/ \
  --reportfile report.txt

But still got the same error when running training.py in the converted folder.

So I tried to downgrade tensorflow to 1.x:
pip3 install tensorflow==1.15
pip gave me some errors about dependencies, so maybe I should have recreated my virtualenv completely with tensorflow==1.15 from the beginning instead of downgrading what was already installed.

But I run train.py anyway to see if it would work and it is running right now. So let's see if it finishes without problems.
