Variable self._runtime referenced before initialization in vot/tracker/__init__.py

[imadtoubal]

Looks like the member variable self._runtime is referenced before being initialized in vot/tracker/__init__.py line 829 resulting in the error:

Traceback (most recent call last):

    if self._runtime.multiobject:
AttributeError: 'MultiObjectTrackerRuntime' object has no attribute '_runtime'

Changing this line 829 from:

        if self._runtime.multiobject:

to:

        if runtime:

solves the issue.

Have there been any successful uses of a multi-object tracker using this toolkit? Can I see some examples?

Multi object wrapper does not really work at the moment. It is also not a good idea unless your tracker has very low resource requirements (no GPUs). We have some examples how to make your tracker truly multi objec in a separate repository (integrations).
