Jupyter Notebook中的模块'spacy.util'没有属性'filter_spans' [英] Module 'spacy.util' has no attribute 'filter_spans' in Jupyter Notebook

问题描述

我有spacy版本2.2.4(也已在2.1.4中尝试过).

I have spacy version 2.2.4 (also tried with 2.1.4).

import spacy
...
result = spacy.util.filter_spans(spans)

错误:模块'spacy.util'没有属性'filter_spans'

我正在从虚拟环境中运行jupyter笔记本，并且还在其中安装了spacy.该文档说应该包括过滤器跨度: https://spacy.io/api/top-level#util.filter_spans

I am running jupyter notebook from a virual environment and installed spacy inside it too. The documentation says filter spans shoud be included: https://spacy.io/api/top-level#util.filter_spans

上下文:尝试从 https://towardsdatascience.com/auto-generate-knowledge-graphs-92ca99a81121

感谢任何帮助.

推荐答案

自己定义函数并使用它:

Define the function by yourself and use it:

def filter_spans(spans):
    # Filter a sequence of spans so they don't contain overlaps
    # For spaCy 2.1.4+: this function is available as spacy.util.filter_spans()
    get_sort_key = lambda span: (span.end - span.start, -span.start)
    sorted_spans = sorted(spans, key=get_sort_key, reverse=True)
    result = []
    seen_tokens = set()
    for span in sorted_spans:
        # Check for end - 1 here because boundaries are inclusive
        if span.start not in seen_tokens and span.end - 1 not in seen_tokens:
            result.append(span)
        seen_tokens.update(range(span.start, span.end))
    result = sorted(result, key=lambda span: span.start)
    return result
