But when I am trying to add custom_hooks I am getting some errors. 13 00:29 浏览量：2 简介：本文将详细介绍如何通过一系列优化策略来提升MMDetection目标检测模型的性能，包括使用SwinTransformer作为Backbone，FPN作为Neck，TOOD模型作为Bbox_head，以及采用Mosaic和Mixup数据增强技术。。通过这些优化措施，我们可以混合类图片数据增强是指类似 Mosaic 和 MixUp 一样，在运行过程中需要获取多张图片的标注信息进行融合。在 OpenMMLab 数据增强 pipeline 中一般是获取不到数据集其他索引的。为了实现上述功能，在 MMDetection 复现的 YOLOX 中提出了 MultiImageMixDataset 数据集包装器的概念。 You signed in with another tab or window. 使用过程中需要注意配置文件中算法组件要和 Detectron2 中的相同。 You signed in with another tab or window. Use Mosaic augmentation¶ If you want to use Mosaic in training, please make sure that you use MultiImageMixDataset at the same time. Taking the ‘Faster R-CNN’ algorithm as an example, you should modify the values of train_pipeline and train_dataset in the config as below: Hi Ima unable to find out suitable note in documents or in forums/question as to how to use mosaic other than what is mentioned that is to use Multiimage data set, but how to use this dataset is al Welcome to MMDetection’s documentation!
