【问题描述】：

我遇到了这个错误问题，我在 jupyter notebook 的基础（root）环境中运行了这个脚本，日志说 gensim 库已经安装并且我已经运行了命令 !pip install gensim 在我导入之前，还是无法导入，报错ModuleNotFoundError: No module named 'gensim'

!pip install gensim
import gensim
from gensim.models import KeyedVectors
model = KeyedVectors.load('model_fasttext2.vec')
model.vector_size

有没有人可以解决这个问题？非常感谢您的帮助，这将有助于我的论文工作，感谢您的关注

【参考方案1】：

您的 jupyter 实验室可能运行的是基本内核，而不是虚拟环境的内核。

执行以下检查：

import sys
sys.executable

进入我的笔记本并得到结果

'/anaconda3/bin/python'

如果你得到的是上面的而不是下面的，那就意味着你使用了错误的内核。

'/anaconda3/envs/myenv/bin/python'

您可以通过为您的新环境创建一个新的 iPython 内核来解决这个问题。阅读更多here。

conda install -n myenv ipython
conda activate myenv
python -m ipykernel install --user --name myenv --display-name "Python (myenv)"
```Then, to run Jupyter Lab in the new environment:

【讨论】：

你也可以this

按照@Azy-Crw4282 的建议，在您的笔记本中，您现在可以使用%pip 魔法，请参阅here 安装到当前内核正在使用的环境中。在你的笔记本中，运行%pip install gensim。

抱歉，在编辑时间到期之前我没有发现拼写错误。那应该是“...在您的笔记本中，您现在可以使用...”。

感谢您的回答，我正在检查环境，它是错误的，不是我要求的基本（root），我通过将其更改为基本内核来修复它
