AttributeError: 'CombinedEvaluations' object has no attribute 'evaluation_modules'

Hi, I tried to run the following script by combining two metrics, but the error occurred:

If we use a list format for evaluations, it works fine, but I think we should also support tuple format, which work in the same way as list. This can be easily achieved by modifying the following section.

May I create a PR?
