Training Instance Segmentation Models Using Mask R-CNN on the NVIDIA Transfer Learning Toolkit

Following the guide to do Mask R-CNN training had an error for ModuleNotFound No module named third party with references to user vpraveen. Others are having the same error with details at TLT V2.0 Classification - #9 by Morganh

Given the nature of running this from a provided nvidia docker container not sure what to resolve.

Any suggestions?
