python - 升级到 PyTorch 1.9 ImportError 时的潜在错误：无法从“torch._six”导入名称“int_classes”

问题描述

我使用安装 PyTorch

$ pip install torch==1.9.0+cu111 torchvision==0.10.0+cu111 torchaudio==0.9.0 -f https://download.pytorch.org/whl/torch_stable.html
I get this error:
(proxy) [jalal@goku proxynca_pp]$ CUDA_VISIBLE_DEVICES=0,1 python train.py --dataset cub  --config config/cub.json --mode train --apex --seed 0
Traceback (most recent call last):
  File "train.py", line 3, in <module>
    import dataset
  File "/scratch3/research/code/fashion/proxynca_pp/dataset/__init__.py", line 6, in <module>
    from . import utils
  File "/scratch3/research/code/fashion/proxynca_pp/dataset/utils.py", line 8, in <module>
    from torch._six import int_classes as _int_classes
ImportError: cannot import name 'int_classes' from 'torch._six' (/scratch3/venv/proxy/lib/python3.8/site-packages/torch/_six.py)

代码来自此 GitHub 存储库。我应该更改代码中的哪些内容才能使其正常工作？

(proxy) [jalal@goku proxynca_pp]$ pip freeze
h5py==3.4.0
numpy==1.21.2
Pillow==8.3.2
scipy==1.7.1
torch==1.9.0+cu111
torchaudio==0.9.0
torchvision==0.10.0+cu111
tqdm==4.62.2
typing-extensions==3.10.0.2

解决方案

最简单的解决方案是设置int_classes = int而不是从_six.
