python - ImportError：DLL 加载失败 sklearn 或 scipy

问题描述

好的，我在 GitHub 和 Stackoverflow 上看到了至少 8 个版本的问题，但没有解决方案。此外，它似乎比过去更晚出现（参见最后的参考资料）

当我尝试简单导入 Sklearn 时，我不断收到“导入错误：DLL 加载失败”

import scipy
# works
import sklearn
# crashes
import scipy.linalg
# crashes
print(sklearn.__version__)

完整的错误输出：

ImportError: DLL load failed: The specified module could not be found.

我知道这是指这是一个 SciPy 问题，但我无法终生修复它。我已经阅读了几乎所有问题，但没有解决办法。我努力了：

我已经尝试了更多与包、路径和安装相关的东西，但 DLL 加载错误仍然存​​在。如何解决此错误？有谁知道这是什么原因？从网上看，它似乎与 Windows 10、PyCharm 和 SciPy 直接相关

环境信息：

这是所有问题和 GitHub sklearn 家伙谈论它的链接，但他们说这是一个“使用错误”。这些都没有给我任何解决方案

导入 scikit-learn 模块时出错

sklearn。ImportError：DLL 加载失败

从 SciPY 导入某些模块时出现 ImportError

ImportError：DLL 加载失败，使用 import sklearn

标签： pythondllscikit-learnscipy

解决方案

似乎这是一个 Windows、PyCharm 和 Sklearn 组合问题。我切换到运行 Pycharm 和 Sklearn 的 Linux VM，它运行良好。
