3.1 class torchvision.datasets.ImageFolder 默认读取图像数据方法: __init__( 初始化) classes, class_to_idx = find_classes(root) :得到分类的类别名(classes)和类别名与数字类别的映射关系字典(class_to_idx) 其中classes (list): List of the class names. 其中class_t...

find_unused_parameters=True的设置会带来额外的运行时开销(而且还不小)。 一种更好的办法是构建一个相同的计算图,用0和1这些选择变量来执行选择操作,这样就不用设置find_unused_parameters参数了。例如: from torch.nn import Module from torch import nn import torch class Net(Module): def __init__(self...
在实现这个的过程中，我们调用了一个叫做find_topo_sort的函数，对以这个输出节点output_node为起始点...

API, which sets the is_traceable class attribute on a torch.autograd.Function class was deprecated in 2.3 and is now being deleted. This API does not do anything and was only meant for internal purposes. The following raised an warning in 2.3, and now errors because the API has been ...
