没有名为 'gensim' 的模块，但已经安装了它

Question

我遇到了这个错误问题，我在基本（根）环境的 jupyter notebook 中有运行这个脚本，日志说 gensim 库已经安装，我有运行命令 !pip install gensim 导入之前，还是导入不了，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

有没有人可以帮助解决这个问题？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

可能是您的 jupyter 实验室运行基本内核而不是虚拟环境的内核。

通过执行以下操作进行检查：

import sys
sys.executable

进入我的笔记本并得到结果

'/anaconda3/bin/python'

如果你得到上面的而不是下面的那么这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 内核来解决它。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:

没有名为 'gensim' 的模块，但已经安装了它

No module named 'gensim' but already installed it
