Why can’t training start?

[piwawa]

The epoch 0 has been going on for 2 days. I have filled in the path correctly in train.txt and text.txt, the dataset has 330k videos and has been preprocessed. If I select some data from train.txt, it can start training immediately. Why can't use a large dataset to train?

DataSet里的continue打一下断点，原项目写的数据加载方式总会跳过异常，变成无效死循环
