Problem  running "Run Dense reconstruction.ipynb'

Hi, I`m testing the dense reconstrucion notebook but I found some problems importing OutputCapture and db_from_existing_poses. Moreover, 'config = dim.Config(params)' gives this error message: 'AttributeError: module 'deep_image_matching' has no attribute 'Config' ' . Does anybody knows how to fix these issues? 
Thnks
