🌈你好呀！我是是Yu欸 🌌 2024每日百字篆刻时光，感谢你的陪伴与支持 ~ 🚀 欢迎一起踏上探险之旅，挖掘无限可能，共同成长！

写在最前面

运行代码时，报错。

代码示例2：细领域分词（如果用户明确分词领域，推荐使用细领域模型分词）

import pkusegseg = pkuseg.pkuseg(model_name='medicine')  # 程序会自动下载所对应的细领域模型
text = seg.cut('我爱北京天安门')              # 进行分词
print(text)

解决方案

Downloading: “https://github.com/lancopku/pkuseg-python/releases/download/v0.0.16/medicine.zip” to /home/tjh/.pkuseg/medicine.zip

搜索下载https://github.com/lancopku/pkuseg-python/releases/download/v0.0.16/medicine.zip
然后解压，并将压缩包+解压后文件夹，放到文件夹/home/tjh/.pkuseg/medicine.zip下。
然后就完美解决啦！！！嘿嘿

记得解压，否则报错：

Traceback (most recent call last):File "/home/tjh/wyt/CT-base/4-2.Seq2seq_Att/load_data.py", line 41, in <module>seg = pkuseg.pkuseg(model_name='medicine')File "/home/tjh/miniconda3/envs/pytorch1.12_gpu/lib/python3.9/site-packages/pkuseg/__init__.py", line 239, in __init__self.postprocesser = Postprocesser(None, other_names)File "/home/tjh/miniconda3/envs/pytorch1.12_gpu/lib/python3.9/site-packages/pkuseg/__init__.py", line 148, in __init__with open(other_name, "rb") as f:

pkuseg是什么？

PKUSEG 是一个由北京大学开发的多领域中文分词工具。这个工具在分词精度上比很多流行的中文分词工具都要优秀，特别是在处理不同领域的文本时，因为它支持对特定领域的文本进行训练和优化。下面是一些PKUSEG的关键特性：

多领域分词：PKUSEG 支持多种领域的分词，包括但不限于通用文本、网络文本、旅游、新闻等，可以根据特定的领域数据进行优化。
高精度：该工具使用了基于深度学习的模型，与传统的基于规则和统计的分词工具相比，能更好地处理复杂的中文文本和歧义现象。
易于使用：PKUSEG 提供了简洁的 API，便于在Python环境中直接使用。用户可以很容易地集成和部署在自己的应用程序中。
自定义模型训练：用户可以使用自己的标注数据来训练专门的分词模型，进一步提升分词效果在特定应用场景中的表现。
开源：PKUSEG 是开源软件，任何人都可以使用、修改和分发，这为开发者提供了极大的灵活性和扩展性。

使用PKUSEG进行中文分词非常简单，一般包括安装、模型选择、文本分词等步骤。这样的工具非常适合需要处理具体领域中文文本的开发者和研究人员。

报错原因

你的代码试图从GitHub下载一个名为"medicine.zip"的文件，但是在SSL证书验证过程中出现了错误。这可能是由于你的网络环境中的SSL证书问题，或者是因为你的Python环境中缺少某些必要的证书。

这里我的问题是第一个，因此直接下载后复制到该区域即可。

你可以尝试以下几种解决方案：

如果你在公司或学校网络环境中，可能存在网络策略阻止了你的下载请求。你可以尝试在其他网络环境中运行你的代码。
你可以尝试更新你的Python环境中的certifi库。这个库包含了Python需要的SSL证书。你可以在终端中运行以下命令来更新这个库：

pip install --upgrade certifi

如果以上方法都不能解决问题，你可以尝试禁用SSL证书验证。但是请注意，这种方法可能会带来安全风险。你可以在你的代码中找到所有的requests.get或requests.post调用，然后添加一个参数verify=False来禁用SSL证书验证。例如：

requests.get(url, verify=False)

请注意，这种方法可能会导致你的代码在某些环境中无法正常工作，因为它依赖于你的网络环境是否允许未经验证的SSL连接。
