When importing OperatorAsModule using code from odl.contrib.torch import OperatorAsModule, I get the error below:

ImportError: cannot import name 'OperatorAsModule' from 'odl.contrib.torch'

My environments are：

Linux: Ubuntu 20.04
python: 3.8.5
pytorch: 1.7.1
odl: 1.0.0.dev0

What's the problem？

The error was caused by dival script. After I reinstall the dival package using pip, The error dissappeared.
