python - 错误 : Class advice impossible in Python3 topia. termextract

Question

我正在执行 nlp 任务。我为topia.termextract 编写了以下代码。执行时显示错误。如果您建议解决错误，这将很有帮助。

from topia.termextract import extract
from topia.termextract import tag

# Setup Term Extractor
extractor = extract.TermExtractor()

# Some sample text
text ='''
Police shut Palestinian theatre in Jerusalem.

Israeli police have shut down a Palestinian theatre in East Jerusalem.

The action, on Thursday, prevented the closing event of an international
literature festival from taking place."""

# Extract Keywords
keywords_topica = extractor(text)
print(keywords_topica)

我在 google colab 中使用 Python 3。

     TypeError: Class advice impossible in Python3.  Use the @implementer class decorator instead.

为了解决这个问题，我添加了以下行:from zope.interface import implementer二者皆是:~/.local/lib/python3.8/site-packages/topia/termextract/extract.py和:~/.local/lib/python3.8/site-packages/topia/termextract/tag.py.
然后在extract.py中，我改了

class TermExtractor(object):
    zope.interface.implements(interfaces.ITermExtractor)

到:

@implementer(interfaces.ITermExtractor)
class TermExtractor(object):
    ...

同样，在 tag.py 中，

class Tagger(object):
    zope.interface.implements(interfaces.ITagger)

到:

@implementer(interfaces.ITagger)
class Tagger(object):
    ...

希望这可以帮助!
