Unable to attain detection on custom object

[phsilvarepo]

Hello there,

I have been working on a custom DOPE detector for a drill, but I seem to be stuck with bad inference results not quite sure why. I have generated the synthetic data using Issac Sim, more specifically: Synthetic Pose Data Generation. As for the training I have generated 20K images and trained for 60 epochs. When it comes to the inference I keep getting "incomplete cuboid detection". The images I used for inference were some of the training images. Beneath I display the config file. Would really appreciate some help. I could generate a new dataset with less flying distractors since it could be due to the complexity but kinda unsure where to go from now. Thanks.

Example of synthetic images:

I have a comment about scaling of generated dataset, can you share with us the command for data generation, and which inference script did you use to get results, since there are two scripts one in inference folder and the other in the training folder.

Note from issues: you should use train2 folder to train

Hello @intelligencestreamlabs,

To generate the dataset, as mentioned I utilized this package. In the terminal I ran:

./python.sh  standalone_examples/replicator/offline_pose_generation/offline_pose_generation.py --writer DOPE --num_mesh 0 --num_dome 20000

This package utilizes Issac Sim 2023.1.1 to generate the data for DOPE training. As for the inference I ran inference/inference.py. I have also noted from other issues the current train/train.py script seems to be broken, I have started training with an older version of the repository. I did not try train2 version but does this script in the current repo work? I can try it later but for now will continue to try an older version.

Thanks for your time

Edit: I have also tried to simplify the generated data, to only 5 flying distractors but this changed nothing in the inference results
