my_dataloader = DataLoader( dataset=torch_dataset, batch_size=4, collate_fn=lambda x: x, drop_last=True ) for i in my_dataloader: print('*' * 30) print(i) a = i a 然后,查看视频: 0 3. 自定义collate_fn参数 现在结合上面的步骤,我们自定义自己的参数,然后实现默认的效果。大概代码如下...

data = pd.concat([dataset_data,dataset_target],axis = 1) 数据集共有150个样本、四个特征和一个类别标签: 我们采用一对多(OvA策略)结合逻辑回归解决这个多分类问题,先介绍一下手推的方式,建模过程与二分类是一样的,只不过我们需要注意一下OvA策略的思想。
