import ResNet_18 DeepStream sample in DIGITS


I have installed digits 6.1.1 on my host machine with NvCaffe and Tensorflow support.
I would like to make some test with ResNet_18 detection net used in DeepStream sdk nvgstiva-app for veichle detection.
It’s possible to import this RSnet pretrained network (ResNet_18_threeClass_VVGA_pruned.caffemodel and ResNet_18_threeClass_VVGA_pruned.prototxt) in Digits ?
Can I train this network with my own veichle dataset in Digits?
After train can I export from Digits and run again with DeepStream nvgstiva app again ?

Thnxss in advance any suggestion appreciated.
