@Morganh Even though I have updated the ~/.tlt_mounts.json file, while the entire folders are not getting mounted in the newly launched container for tlt mask_rcnn training.
I am already inside a container and from there i am trying to run tlt mask_rcnn train after updating the ~/.tlt_mounts.json file , but inside the newly launched container only empty directory are getting created with the source name provided in ~/.tlt_mounts.json file.
