我在加载文档索引时遇到麻烦。 我正在测试我的代码，所以我设置了
batch_size = 4
number_of_sentences_in_document = 84
number_of_words_in_sentence = 80
将一个mini_batch汇总为80 * 84 * 4个文档索引。
问题在于，当我将这些索引数据集转换为如下所示的DataLoader时 并尝试遍历Trainloader，结果产生了很多错误消息。
DataManager = DS.NewsDataset(data_examples_gen, Vocab)
trainloader = torch.utils.data.DataLoader(DataManager, batch_size=Args.args.batch_size, shuffle=True, num_workers=32)
下面是错误消息。

以退出代码1完成的过程
我认为这是某种内存问题，所以我尝试了同样的事情 一个文档只有两个句子，它起作用了。 但是，我希望随着 batch_size最多为32或64， 每个文档的句子数最多为84 每个句子的单词数最多为84。
我尝试了
$ ulimit -n 10000
但是那个没有用。
如何解决此问题？ 有任何想法吗？
