import datetime
import time
from torchtext.data import Field, Dataset, Example, Iterator
import copy
import torch.nn as nn

当试图导入以上包的时候，出现了报错

     13 import datetime
     14 import time
---> 15 from torchtext.data import Field, Dataset, Example, Iterator
     16 import copy
     17 import torch.nn as nn

ImportError: cannot import name 'Field' from 'torchtext.data' (/usr/local/lib/python3.9/dist-packages/torchtext/data/__init__.py)

初步尝试

根据网上的教程，尝试命令“!pip install torchtext==0.9.0”

此后再次运行from torchtext.data import Field, Dataset, Example, Iterator，依然会出现报错

ImportError: cannot import name 'Field' from 'torchtext.data' (/usr/local/lib/python3.9/dist-packages/torchtext/data/__init__.py)

尝试from torchtext.legacy.data import Field, Dataset, Example, Iterator，依旧报错
