Ah, finally I'm on the same error. Thank you for your help debugging! I'll figure this out and close this asap.

@bhairavmehta95 I am getting the same error when trying to evaluate, here's the full stack trace:

It looks like some ROS message types are missing.

Hi @hristo-vrigazov , thanks for testing. Yes - you are correct. This has to do with the way / order that the various environment / bash files are sourced. We should have a solution within the hour.

liampaull commented 6 years ago

I think I got it - the source commands in upstream dockerfile are out of order. See commit: https://github.com/duckietown/challenge-aido1_LF1-template-ros/commit/e89d9bcffac4de681d6126c5e26ceb472ef34bee

@bhairavmehta95 I'm back to getting the old error - it must have to do with the docker builds, I'm not sure I'm doing it right - can you make sure that the building is happening properly ?

One piece of advice: always run "evaluate" locally - it usually is easier than debugging remote executions.
