How can I choose a specific backend?

[haloproof]

I have several available backends (tensorflow.compat.v1, pytorch, etc.), but how to choose a specific one? When I run my program it selects tensorflow.compat.v1 by default, but I want to use pytorch.

Use the DDE_BACKEND environment variable:

import os

os.environ['DDE_BACKEND'] = 'tensorflow.compat.v1' print(os.getenv('DDE_BACKEND'))
