Describe the bug
Running a model without an additional model for sensitivity maps causes the following issue:
NotImplementedError: You must implement either the backward or vjp method for your custom autograd.Function to use it with backward mode AD.

To Reproduce
Running a model without an additional model for sensitivity maps.

Expected behavior
Not to get the error.

Additional context
Remove openvivo functionality, inspect later.

Hello, @georgeyiasemis
Could you please help me to reproduce this error? I can't find this case in tests for any 'RIM' or 'Unet2d' model.
