Test if notebook is running on Google Colab

Question

How can I test if my notebook is running on Google Colab?

I need this test as obtaining / unzipping my training data is different if running on my laptop or on Colab

Answer 1

There is also the possibility to check the ipython interpreter used. I think it is a little bit more clear and you don't have to import any module.

if 'google.colab' in str(get_ipython()):
  print('Running on CoLab')
else:
  print('Not running on CoLab')

If you need to do it multiple times you might want to assign a variable so you don't have to repeat the str(get_ipython()).

RunningInCOLAB = 'google.colab' in str(get_ipython())

RunningInCOLAB is True if run in a Google Colab notebook.
