Python 在Jupyter笔记本中安装SpaCy

我试图安装SpaCy进行柠檬化，但它不起作用

首先，我安装spacy：

pip install -U spacy

这导致了以下结果：

工作正常，不会发生错误。 然后我想加载一个数据包：

nlp = spacy.load('de_core_news_sm') 

出现以下错误：

---------------------------------------------------------------------------

OSError:[E050]找不到模型“de_core_news_sm”。它似乎不是快捷链接、Python包或数据目录的有效路径。

有人能帮我解决这个问题吗？我试了好几个小时，但没有找到解决办法

谢谢大家!

要加载模型，如果您是在本地机器上（而不是在google colab上）下载，则需要先下载模型。那以后呢

pip install -U spacy

您需要使用

python -m spacy download de_core_news_sm

那么

---

谷歌合作实验室 如果在谷歌colab中尝试

pip install -U spacy
import spacy.cli
spacy.cli.download("de_core_news_sm")

---

您还可以添加虚拟环境，然后在虚拟环境中激活后使用spacy

python3 -m venv <name_of_virtualenv>
# to activate 
source /pathtovirenc/<name_of_virtualenv>/bin/activate

#then use the above commands
pip3 install -U spacy
python3 -m spacy download de_core_news_sm

python3-m静脉
#激活
source/pathtovirenc//bin/activate
#然后使用上述命令
pip3安装-U空间
python3-mspacy下载核心新闻

您需要先下载模型

python-mspacy下载核心新闻

Thnk您的答案。下载模型后，我必须将其放置在何处？我必须下载哪些文件？但这正是我所做的。首先使用

pip install-U spacy

安装spacy，然后使用

python-m spacy download de_core\U news\U sm

下载软件包。但这将导致错误。所以我不明白这个问题。我在google colab中没有做任何事情，但在jupyter笔记本中。我必须在控制台中插入安装和下载cammand吗？您是否使用python3，然后在python中编写python3和pip3，piptry创建一个虚拟环境，然后在激活后将spacy放入其中，更新答案以显示如何添加虚拟环境，并使用

import sys print（sys.version）

I get

3.6.10 | Anaconda，Inc.

如果我使用pip3，它会抛出一个名为：

SyntaxError:invalid syntax

的错误。我将尝试添加虚拟环境linux、win或mac上的操作系统是什么？

pip install -U spacy
import spacy.cli
spacy.cli.download("de_core_news_sm")

python3 -m venv <name_of_virtualenv>
# to activate 
source /pathtovirenc/<name_of_virtualenv>/bin/activate

#then use the above commands
pip3 install -U spacy
python3 -m spacy download de_core_news_sm
