如何修復 pycharm 中的此導入錯誤？

Question

我最近開始使用 python 和 pycharm，只是為了玩弄它。 但是我在導入 sklearn 模塊時遇到了問題。 所有其他模塊都可以正常工作，只有這個（sklearn）不是很痛苦。 我嘗試導入的模塊如下：

from sklearn.model_selection import cross_validate
from sklearn.model_selection import train_test_split
from sklearn.neighbors import KNeighborsClassifier as KNeighborsClassifier
from sklearn import svm, neighbors
from sklearn.ensemble import VotingClassifier, RandomForestClassifier

運行它會得到以下輸出：

我已經被困在這一段時間了，任何幫助都是有用的！ 先感謝您

Answer 1

很有可能這是 PYTHONPATH 問題，您的 pyCharm 無法與安裝了所有必需庫的正確 Python 版本（或虛擬環境）通信。 您可能需要通過進入首選項> 項目> 項目解釋器然后選擇正確的python 二進制文件來配置pyCharm

我會去這里： https : //scikit-learn.org/stable/install.html檢查您的安裝並在必要時重新安裝。 該站點還指出，如果 Numpy 或 Scipy 是從源代碼重新編譯的（不確定這是否是您的情況），您可能會遇到問題。
