導入 Sklearn 時出現錯誤

Question

嘗試將import sklearn.metrics.pairwise as pw時出現錯誤，我該如何解決？

完全錯誤： ImportError: DLL load failed while importing _arpack: 找不到指定的程序。

導入：將 sklearn.metrics.pairwise 導入為 pw

嘗試刪除並重新安裝 sklearn package

conda remove --force numpy, scipy, scikit-learn

或者

conda remove scikit-learn

並使用pip安裝

pip install -U scikit-learn
