我在Jupyter Notebook的基本(root)环境中运行脚本时遇到了这个错误问题，日志显示gensim库已经安装，并且我在导入它之前已经运行了命令!pip install gensim，但它仍然无法被导入，错误显示ModuleNotFoundError: No module named ‘gensim’

回答：
可能是您的Jupyter Lab在运行基本内核而不是虚拟环境的内核。
可以通过以下方式检查：
import syssys.executable在我的笔记本中输入上述代码并得到结果
'/anaconda3/bin/python'如果您得到上述结果而不是下面的结果，那么意味着您使用的是错误的内核。
'/anaconda3/envs/myenv/bin/python'您可以通过为新环境创建一个新的iPython内核来解决这个问题。更多信息请阅读这里。
conda install -n myenv ipythonconda activate myenvpython -m ipykernel install --user --name myenv --display-name "Python (myenv)"```然后，在新环境中运行Jupyter Lab：
