如何修复pycharm中的导入错误？

Question

我最近开始使用python和pycharm，只是想在这上面玩一玩。但是我在导入sklearn模块时遇到了一个问题。所有其他模块都工作得很好，只是这一个（sklearn）不是一个难题。我尝试导入的模块如下所示：

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

运行此命令将产生以下输出：

我已经被困在这个一段时间，任何帮助都是感激的！先谢谢你

Answer 1

这很可能是PYTHONPATH问题，您的pyCharm无法与安装了所有必需库的正确python版本（或虚拟环境）对话。您可能需要通过转到首选项>；来配置pyCharm；项目>；项目解释器，然后选择正确的python二进制文件

我会去这里：https://scikit-learn.org/stable/install.html 检查您的安装，必要时重新安装。 该网站还声明，如果Numpy或Scipy是从源代码处重新编译的（不确定这是否是您的情况），您可能会遇到问题
