Is it possible to set environment variables in Google's Colaboratory?

Question

I am running some Python scripts in Google's Colaboratory platform. Now, I need to set some environment variables of the system. Like the following shows:

!export PATH=drive/app/tf-models-fork/research;drive/app/tf-models-fork/research/object_detection;drive/app/tf-models-fork/research/slim;$PATH

I tried to add the location to the variable PATH. However, I am getting the following errors:

/bin/sh: 1: drive/app/tf-models-fork/research/object_detection: Permission denied
/bin/sh: 1: drive/app/tf-models-fork/research/slim: Permission denied
/bin/sh: 1: drive/app/tf-models-fork/research: Permission denied

Is there any way to set the environment variables in this platform?

Answer 1

I normally set the PATH with os.environ, like this:

import os
os.environ['PATH'] += ":/usr/local/go/bin"
