- Check the configuration file for cascade rcnn in PaddleDetection to ensure the data format and preprocessing steps match your dataset. Verify that the evaluation script is correctly loading the trained model weights and not just initialized ones. Look for similar issues in the repository's issue tracker or documentation about common pitfalls when training with custom datasets.
