I want to install tensorflow version 1.14 in Google colab but failed

Question

I need to test a code in Google colab which is not supported in tf2(for tf.ceil is not supported in tf2), so I want to install tensorflow in version 1.14. I use pip3 and pip to install tensorflow, all of them install tf successfully, but as I do this:

import tensorflow as tf
tf.__version__

It returns:

'2.2.0-rc3'

And I have clear sys.path:

import sys
sys.path

It returns:

[]

How can I install tensorflow in version 1.14?

Answer 1

The easiest way to ensure you work with TF v1 is to simply run the

%tensorflow_version 1.x

line before you import TensorFlow.

Colab already builds TF from source so Google recommends against using pip to install TF as you may incur performance problems.
