沒有名為“gensim”的模塊，但已經安裝了它

Question

我遇到了這個錯誤問題，我在基本（root）環境中的 jupyter notebook 中運行了這個腳本，日志說已經安裝了 gensim 庫，我在導入之前運行了命令!pip install gensim ，但它仍然無法導入，錯誤為ModuleNotFoundError: No module named 'gensim'

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

有沒有人可以幫助解決這個問題？ 我將非常感謝您的幫助，這將有助於我的論文工作，感謝您的關注

Answer 1

可能是您的 jupyter 實驗室運行的是基礎內核，而不是虛擬環境的內核。

通過執行以下操作進行檢查：

import sys
sys.executable

進入我的筆記本並得到結果

'/anaconda3/bin/python'

如果你得到上面的而不是下面的，那么這意味着你使用了錯誤的內核。

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

您可以通過為您的新環境創建一個新的 iPython 內核來解決它。 在這里閱讀更多。

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:
