EOFError: Ran out of input

本人正在学习机器学习，在利用miniImageNet尝试训练一种元学习分类器，执行代码为

python train_classifier.py --config configs/train_classifier_mini.yaml

但是出现了大量报错：

(pytorch) C:\Users\13544\Desktop\few-shot-meta-baseline-master>Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "D:\ProgramData\Anaconda3\envs\pytorch\lib\multiprocessing\spawn.py", line 105, in spawn_main
    exitcode = _main(fd)
  File "D:\ProgramData\Anaconda3\envs\pytorch\lib\multiprocessing\spawn.py", line 115, in _main
    self = reduction.pickle.load(from_parent)
EOFError: Ran out of input

请问各位这些是什么意思，且如何解决？
