no arguments supplied to model = infer_engine.initialize_model_from_cfg()

[bmabir17]

On line 103 in inference.py the weights arguments are not inserted.
The correct line should be
model = infer_engine.initialize_model_from_cfg(args.weights)

Edit:
After giving the weights file the following error occurs
'

I am using the docker image of the detectron. And was able to run the demo of infer_simple.py on a picture. so i think the detectron setup is not a problem.
