Question

好的，我已经看到至少有8个版本的该问题散布在GitHub和Stackoverflow上，没有任何解决方法。此外，它似乎比过去弹出得更多（请参阅最后的参考资料）

当我尝试简单地导入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__)

完整错误输出：

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

我知道这是一个SciPy问题，但我一生无法解决。我已经读完几乎所有问题都没有解决办法。我尝试过：

使用标准软件包卸载并重新安装SciPy，scikit-learn，numpy等。
使用正确的文件名pip install --upgrade --force-reinstall "numpy‑1.16.3+mkl‑cp37‑cp37m‑win32.whl"从https://www.lfd.uci.edu/~gohlke/pythonlibs/#numpy卸载并重新安装所有带有非官方软件包（.whl文件）的软件包
将SciPy和scikit-learn降级到早期版本
我已经在PyCharm中销毁并创建了新的虚拟环境，并尝试通过Project Interpreter使用其安装（是的，我已经仔细检查了解释器路径是否正确）

我尝试了更多与软件包，路径和安装相关的事情，但是DLL加载错误仍然存在。如何解决此错误？有谁知道是什么原因造成的？从网上来看，它似乎与Windows 10，PyCharm和SciPy直接相关

环境信息：

运行Windows 10的标准Dell
运行Python 3.7.7的PyCharm 2020 Pro Edition
scipy 1.4.1（尝试1.4.0）
scikit学习0.23.1（尝试0.22.1？和0.21.3）
numpy 1.18.4（在第一个链接中建议尝试numpy + MKL .whl软件包）

这里是所有问题，还有指向sklearn的GitHub sklearn的链接，但他们说这是“使用错误”。这些都没有给我任何解决办法

Error importing scikit-learn modules

https://github.com/scikit-learn/scikit-learn/issues/15899

sklearn. ImportError: DLL load failed

ImportError when importing certain modules from SciPY

ImportError: DLL load failed, with import sklearn

Answer 1

这似乎是Windows，PyCharm和Sklearn组合的问题。我切换到运行Pycharm和Sklearn的Linux VM，它运行良好。

ImportError：DLL加载失败sklearn或scipy
