Warning:optimizer contains a parameter group with duplicate parameters

I follow you code, and train a model. But it results may not meet the need.

I eval the model you share .

bash shells/eval_syn2city.sh

your share model.
in syn2city : 19 classes : meanIout: 0.4771
I train the model:
in syn2city : 19 classes : meanIout: only: 0.46.7

in the train. I find the warning, So I want to know if it may cause the result drop.

Hi, your achieved result (46.7/19*16=55.5 in 16 classes) is already slightly better than what we reported in the paper 55.0 mIoU.

As we mentioned in the ReadMe file Table, the paper's result(55.0) is based on 5 different runs. The provided model~(56.3) is our best run.
