NoneType object has not attribute get

Tensorhive works great but I get the error messages below on every startup. Everything seems to work fine. Is this something I should worry about?

This line is causing the error: https://github.com/roscisz/TensorHive/blob/master/tensorhive/core/services/UsageLoggingService.py#L237 Would it make sense to change it to:

# gpu_data = infrastructure[hostname].get('GPU').get(uuid)
gpu_data = infrastructure[hostname].get('GPU', {}).get(uuid)
