Name: File building error
Title: General File Building error (likely project 2)
About: when using colcon build, it simply doesn't work due to not loading. It will compile for 2-6 mins and fail due to some sort of fatal error in the "object detector" file.

steps to reproduce:

1. cd into training_ws and then src
2. run colcon build
3. find fail
