BackgroundGenerator(super().__iter__())是在使用PyTorch的DataLoader时,通过prefetch_generator库中的BackgroundGenerator类来实现数据加载的优化。这个代码片段可以在自定义的DataLoaderX类的__iter__方法中使用,用于返回一个经过BackgroundGenerator包装的迭代器。BackgroundGenerator类可以在后台异步地预取数据,从而提高数据加载的速度。这种优化可以在处理大规模数据集时特别有用,可以减少数据加载的等待时间,提高训练效率。\[1\]\[2\]你可以在这篇博客文章中了解更多关于如何使用BackgroundGenerator来优化PyTorch DataLoader的信息:https://blog.csdn.net/weixin_44008424/article/details/110764494\[3\]
