Problem Statement

I am currently working on a project involving training a model, and I have encountered an issue during the evaluation step. I would greatly appreciate your assistance in resolving this problem.

Successful Training Process

As shown in the screenshot above, the training process appears to have completed successfully. The model checkpoints are being saved without any issues.

Error in the Evaluation Step

In the evaluation step, I encounter the following error:

Could not set up the required agent:
> [Errno 2] No such file or directory: 'leaderboard/team_code/interfuser.pth.tar'

Additional Information

• Environment: Conda environment created and training performed on 1 GPU.
• Following Changes made out of README - Batch_size set to 8 (CUDA Out of Memory) && world_size() is set to 1 (1 GPU related error, mentioned in other commits)

Thank you in advance for your assistance!

Hi!

You need to move the saved checkpoint to the path leaderboard/team_code/interfuser.pth.tar

Pretrain weights

I downloaded the pre-trained weights under 'Pretrain weights' section in ReadME.md which was downloaded here. The model was moved to leaderboard/team_code/. Then, I ran the model and everything seem fine as of now. Now, The issue is sovled.

I have a quick question on this method: 1) I haven't ran 'train.sh' yet. As of now, I have ran only the data generation part, I was wondering why do I need pre-trained weights for generating data for the training process. 2) Is the pre-trained weights created using the training process of the Interfuser or created using the leaderboard under the carla sim!?

Regards, Naren.
