Question

我无法导入scipy.stats并收到以下错误，但不知何故

import scipy as sp

仍然可以正常工作。

可以导入其他库，例如numpy，pandas。

我尝试在Anaconda中重新安装scipy 1.2.1，降级为scipy 1.2.0，但仍然找不到ImportError指定的过程。

我使用都由Anaconda在原子文本编辑器中安装的python 3.7.3和scipy 1.2.1。

ImportError: DLL load failed: The specified procedure could not be foundใ

Answer 1

谷歌搜索一段时间后，我发现： https://github.com/conda/conda/issues/6396

因为我很拼命所以尝试了。而且有效！我通过删除Anaconda安装的scipy解决了使用预先安装了python的pip来安装scipy。

它以某种方式解决了问题。将会把这个答案留给任何不幸的灵魂。

Answer 2

我在conda仓库中遇到了类似numpy和scipy的问题。它在加载预编译的库时发生。就我而言，它们是lapack_lite和_umath_linalg。如果我卸载conda版本并使用pip版本，则可以正常运行。

解决方案：

$ conda remove --force numpy, scipy
$ pip install numpy, scipy

然后它可以正常运行，因此希望此过程对您有用。但是每个需要这两个软件包的新软件包都将由于安装在回购协议末尾的补丁版本而再次安装conda版本，除非您想手动安装所有依赖项以避免这两个软件包。

Answer 3

我遇到了同样的问题，只是运行 pip instll scipy -U 来更新 Scipy

导入scipy.stats时，获取“ ImportError：DLL加载失败：找不到指定的过程”
