从最近开始，每当我运行笔记本时，我都会收到此错误：

ModuleNotFoundError: No module named 'pytextrank'

这是我笔记本的链接： https ://colab.research.google.com/github/neomatrix369/awesome-ai-ml-dl/blob/master/examples/better-nlp/notebooks/jupyter/better_nlp_summarisers.ipynb#滚动至=-dJrJ54a3w8S

虽然检查显示该库已安装，但 python 导入失败 - 我曾在不同的场景中遇到过此问题，并使用以下方法修复它：

python -m pip install pytextrank

但这没有任何影响，错误仍然存​​在。

这在过去不是问题，同样的笔记本运行良好 - 我认为这可能是一种回归。

有什么想法吗？任何有用的反馈将不胜感激。

这是我调用的代码：

import pytextrank
import sys
import networkx as nx
import pylab as plt

我在 colab 单元中得到了这个：

[nltk_data] Downloading package stopwords to /root/nltk_data...
[nltk_data]   Unzipping corpora/stopwords.zip.

NOTE: If your import is failing due to a missing package, you can
manually install dependencies using either !pip or !apt.

您可以运行一个单元以用于在 Colab 中显式pip安装：pytextrank

!pip install pytextrank

之后，假设mih.json已经创建或上传了一个数据文件，以下代码在 Colab 中运行：

import pytextrank

path_stage0 = "mih.json"
path_stage1 = "o1.json"

with open(path_stage1, 'w') as f:
    for graf in pytextrank.parse_doc(pytextrank.json_iter(path_stage0)):
        f.write("%s\n" % pytextrank.pretty_print(graf._asdict()))

graph, ranks = pytextrank.text_rank(path_stage1)

for rl in pytextrank.normalize_key_phrases(path_stage1, ranks):
    print(pytextrank.pretty_print(rl))

生成此输出：
