Hi davidwu0709, the segnet-console program is compatible with segmentation models using FCN-Alexnet models (or derivatives like FCN-8S). Not sure that it will be able to use this other segmentation model you linked to due to custom layers that it appears to use (it says it uses a modified version of caffe). What you could do, is just run that GitHub code and not use it with segnet-console. It won’t be using TensorRT but you can at least run it.
Alternatively, what I would recommend is trying to follow the segmentation training tutorial with FCN-Alexnet, but using the dataset that you desire.
