Question

在我所有使用依赖scipy的软件包的脚本中（例如sklearn和statsmodels），我都会收到此ImportError。

我卸载了Anaconda并安装了新版本的Anaconda（Windows 10最新版本为2019.03）。我也尝试过创建单独的环境并独立安装scipy，numpy，sklearn，但这也行不通。

from sklearn import preprocessing

问题似乎与不兼容的scipy版本有关，您可以尝试通过以下方式重新安装它：

conda install -f scipy

希望有帮助！

使用依赖于scipy的程序包会引发ImportError（DLL加载失败），即使重新安装Anaconda也是如此
