Description

When running Cells on google Colab, second cell gives error

Environment information

google colab

OS: Linux

$ pip freeze | grep tensor
# your output here

$ python -V
# your output here

For bugs: reproduction and error logs

Steps to reproduce:

If one takes out

if 'google.colab' in sys.modules: # Colab-only TensorFlow version selector
  %tensorflow_version 1.x

---

and restarts runtime and runs
the import error dissapears, but errors regarding attributes unavailable in tf1 appear (e.g. tf1.contrib.eager)

The import error on cell 2 is

ImportError                               Traceback (most recent call last)
