from sklearn import datasets

我无法导入sklearn

这是错误：

当我输入pip install sklearn时，我已经满足要求：

所以我为什么不能使用sklearn，谢谢您的帮助。

编辑：当我在cmd中导入sklearn时没有任何问题，但是，当我使用Jupyter Notebook运行时，出现上述错误。

Answer 1

只需确保库搜索路径中的OpenSlide DLL

否则：下载OpenSlide Windows二进制文件，然后需要将“ bin”文件夹添加到您的环境路径中

Answer 2

通常，当您的计算机上有多个版本的Python时，就会发生这种情况。

尝试通过以下方式安装sklearn

python -m pip install sklearn

如果这将安装新的sklearn，则意味着您的pip和python具有不同的路径，而pip仅为您安装的另一个Python版本安装了sklearn在您的系统中。
