关于训练过程中报错

[Richardsh]

你好!
我训练模型的时候,训练到634epoch的时候,遇到报错,
Traceback (most recent call last):
File "train_lr.py", line 234, in
main()
File "train_lr.py", line 69, in main
i_tb,model_path = train(train_loader, net, optimizer, epoch, i_tb)
File "train_lr.py", line 82, in train
for i, data in enumerate(train_loader, 0):
File "/usr/local/lib/python3.6/dist-packages/torch/utils/data/dataloader.py", line 345, in next
data = self._next_data()
这里有可能是什么原因造成的呢
