问题

i'm having this error problem, i have ran this script in jupyter notebook in base (root) environment, the log said that gensim library has been installed and i have run the command !pip install gensim before i import it, but it still can not be imported, and the error said ModuleNotFoundError: No module named 'gensim'

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

Is there anyone who can help this problem? i will really appreciate your help, it will help my thesis work, thank you for your attention

回答1:

It may be that your jupyter lab maybe running the base kernel and not the kernel of the virtual environment.

Check by doing the following:

import sys
sys.executable

into my notebook and got the result

'/anaconda3/bin/python'

If you get the above instead of the below then that means you're using the wrong kernel.

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

You can solve it by creating a new iPython kernel for your new environment. Read more 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:
