导入错误：无法从“collection.abc”导入名称“defautdict”如何解决？

Question

这是我的错误堆栈 - 我已将我的代码从from collections import Mapping 更改为from collections.abc import Mapping，因为它给出了一个导入错误，但在此之后它现在给出了这个错误-

 File "C:\Users\ankit\Desktop\yt-sum-flask\summarizer.py", line 2, in <module>
    from gensim.summarization.summarizer import summarize
  File "C:\Users\ankit\Desktop\yt-sum-flask\env\lib\site-packages\gensim\__init__.py", line 5, in <module>
    from gensim import parsing, corpora, matutils, interfaces, models, similarities, summarization, utils  # noqa:F401
  File "C:\Users\ankit\Desktop\yt-sum-flask\env\lib\site-packages\gensim\corpora\__init__.py", line 12, in <module>
    from .dictionary import Dictionary  # noqa:F401
  File "C:\Users\ankit\Desktop\yt-sum-flask\env\lib\site-packages\gensim\corpora\dictionary.py", line 11, in <module>
    from collections.abc import Mapping, defaultdict
ImportError: cannot import name 'defaultdict' from 'collections.abc' (C:\Users\ankit\AppData\Local\Programs\Python\Python310\lib\collections\abc.py)

这是我的要求.txt

如何解决这个错误？

Answer 1

也许尝试从集合导入 defaultdict

Answer 2

变化：

from collections.abc import Mapping, defaultdict

到：

from collections import defaultdict
from collections.abc import Mapping

Mapping 和 defaultdict 不再在同一个模块中，因此必须分别导入。
