registrering two grandient with name 'scaleInvariantGradient'

[MrMinemeet]

Hi,

I'm trying to get DeepTAM running but at the moment I'm stuck with the following error message

KeyError: "Registering two gradient with name 'ScaleInvariantGradient' !(Previous registration was in init /home/adas/DeepTAM/deeptam/tracking/python/deeptam_tracker/tracker.py:231)"

Every other problem was more or less easy to find out but this is very hard and I can't get it worked out.

Here would be the full stack trace if it helps: https://pastebin.com/2qu72vnJ

Tensorflow graph reseted

This happens when running the example_basic.py or example_advanced_sequence.py

Hope you have an idea how to fix it

[MrMinemeet]

I don't get the error anymore but didn't actively do anything to fix it. So it's kinda fixed but still if someone would know how to fix it please write it here so that others can see it.
