数据标签的feature是datasets. features.ClassLabel,实例化参数可以使用列表数据类型,其中包含每个标签的名称(如cifar的"airplane","automobile"...),也可以使用int数据类型,直接写入类别数。task_templates传入常见的任务,详见datasets.task,如图像分类任务ImageClassification
每个arrow_dataset都有多少条数据,以及这些数据的feature是什么。 整个数据结构是三层的,我们把每层的type打印出来看一下就知道,第一层也就是所有的数据内容:DatasetDict'>,这里是构造的一个词典类,顾名思义他是把所谓的dataset打包成一个字典结构,第二层也就是数据层,dataset类处理的数据,这里每个都是一个dataset...

Hi @Alberto1404, to load an object detection dataset it's recommended to make use of the metadata feature as explained here. Alberto1404 commented Apr 3, 2023 Thank you @NielsRogge! It works!!! 🎉 1 Contributor mariosasko commented Jul 24, 2023 You can now refer to https://hugging...

Use map() for transformations like tokenization or feature engineering. Leverage built-in methods like shuffle(), filter(), and train_test_split() to prepare the data dynamically without external libraries. In conclusion The load_dataset function is best for getting started quickly with pre-built...
Furthermore, many of these datasets feature a restricted number of supply points, including those from sources such as AMPds2, FIKElectricity, UK-DALE, GREEND, CoSSMic, NOVAREF, DEDDIAG, REFIT, ENERTALK, ADRES, WPuQ, NESEMP, IDEAL, EULP, Elergone, EWELD, and MFRED. The sample size ...
