How to downgrade to tensorflow-gpu version 1.12 in google colab

问题

I am running a GAN which is compatible only with a older version of tensorflow GPU so I need to downgrade tensorflow gpu from 1.15 in google colab to 1.12. I tried using following commands which has been suggested in this thread.

%tensorflow_version 1.x
import tensorflow as tf
print(tf.__version__)

!nvcc --version

After the magic and the version check (which I get tensorflow version == 1.15.2 for now) I install below. After installation of tensorflow ==1.12.2 I restart the runtime as they suggest(I tried otherwise too) and install cuda and restart the runtime again(tried otherwise here also).

!pip install tensorflow-gpu==1.12.2

!wget https://developer.nvidia.com/compute/cuda/9.0/Prod/local_installers/cuda-repo-ubuntu1604-9-0-local_9.0.176-1_amd64-deb
!dpkg -i cuda-repo-ubuntu1604-9-0-local_9.0.176-1_amd64-deb
!apt-key add /var/cuda-repo-9-0-local/7fa2af80.pub
!apt-get update
!apt-get install cuda=9.0.176-1

This way has worked even up untill 2019 but it is not working for me now. I need a solution with using pip or without using pip.

I tried below code as well to uninstall the current version and installed 1.12 but it did not work. And I know that the colab does not recommend installing tensorflow using pip.

!pip uninstall tensorflow-gpu -y
