DLL加载失败：导入scipy时找不到指定的模块

Question

I have installed python with Anaconda on windows 10. I have created a virtual environment with Anaconda called venv . After activating the environment, >>>python gives:

Python 3.6.8 |Anaconda, Inc.| (default, Feb 11 2019, 15:03:47) [MSC v.1915 64 bit (AMD64)] on win32

I have installed scipy in my venv using pip: pip install scipy .

I have set the interpreter in pycharm to the venv python interpreter.

Now, I tried the following in a new module in pycharm:

import scipy    # No error here
from scipy.stats import norm # Here I got the error

Error:

Traceback (most recent call last):
  File "C:/Users/user/Documents/February2019/AVEC2018/ApplyPCA.py", line 11, in <module>
    from scipy.optimize import _hungarian
  File "C:\Users\user\AppData\Local\Continuum\anaconda3\envs\venv\lib\site-packages\scipy\optimize\__init__.py", line 386, in <module>
    from .optimize import *
  File "C:\Users\user\AppData\Local\Continuum\anaconda3\envs\venv\lib\site-packages\scipy\optimize\optimize.py", line 37, in <module>
    from .linesearch import (line_search_wolfe1, line_search_wolfe2,
  File "C:\Users\user\AppData\Local\Continuum\anaconda3\envs\venv\lib\site-packages\scipy\optimize\linesearch.py", line 18, in <module>
    from scipy.optimize import minpack2
ImportError: DLL load failed: The specified module could not be found.

I have followed the instructions here as an attempt to solve the problem.

Therefore, I ran print(os.environ['PATH']) while using the venv python interpreter in cmd (ie, after activating venv ); I copied the following result

C:\Users\user\AppData\Local\Continuum\anaconda3\envs\venv;C:\Users\user\AppData\Local\Continuum\anaconda3\envs\venv\Library\mingw-w64\bin;C:\Users\user\AppData\Local\Continuum\anaconda3\envs\venv\Library\usr\bin;C:\Users\user\AppData\Local\Continuum\anaconda3\envs\venv\Library\bin;C:\Users\user\AppData\Local\Continuum\anaconda3\envs\venv\Scripts;C:\Users\user\AppData\Local\Continuum\anaconda3\envs\venv\bin;C:\Program Files (x86)\Common Files\Oracle\Java\javapath;C:\Program Files (x86)\Intel\iCLS Client\;C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v9.0\bin;C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v9.0\libnvvp;C:\ProgramData\Oracle\Java\javapath;C:\Program Files\Intel\iCLS Client\;C:\Windows\system32;C:\Windows;C:\Windows\System32\Wbem;C:\Windows\System32\WindowsPowerShell\v1.0\;C:\Program Files\MATLAB\R2017a\runtime\win64;C:\Program Files\MATLAB\R2017a\bin;C:\Users\user\.dnx\bin;C:\Program Files\Microsoft DNX\Dnvm\;C:\Program Files\Microsoft SQL Server\130\Tools\Binn\;C:\WINDOWS\system32;C:\WINDOWS;C:\WINDOWS\System32\Wbem;C:\WINDOWS\System32\WindowsPowerShell\v1.0\;C:\Program Files\Git\cmd;C:\cuda7\cuda\bin;C:\Program Files\Weka-3-8;C:\Users\user\Downloads\ffmpeg-20170904-6cadbb1-win64-static\bin;C:\Program Files\Java\jdk1.8.0_144\bin;C:\Program Files\Java\jre1.8.0_144\bin;C:\Program Files\Intel\WiFi\bin\;C:\Program Files\Common Files\Intel\WirelessCommon\;C:\Users\user\Downloads\pandoc-2.1.2;C:\Users\user\AppData\Local\Continuum\anaconda3\Scripts;C:\Users\user\AppData\Local\Continuum\anaconda3;C:\Program Files (x86)\NVIDIA Corporation\PhysX\Common;C:\Users\user\AppData\Local\Programs\MiKTeX 2.9\miktex\bin\x64;C:\Users\user\Downloads\cmake-3.11.2-win64-x64\bin;C:\Program Files (x86)\Intel\Intel(R) Management Engine Components\DAL;C:\Program Files\Intel\Intel(R) Management Engine Components\DAL;C:\Program Files (x86)\Intel\Intel(R) Management Engine Components\IPT;C:\Program Files\Intel\Intel(R) Management Engine Components\IPT;C:\WINDOWS\system32;C:\WINDOWS;C:\WINDOWS\System32\Wbem;C:\WINDOWS\System32\WindowsPowerShell\v1.0\;C:\WINDOWS\System32\OpenSSH\;C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v9.0\extras\CUPTI\libx64;C:\Program Files\NVIDIA Corporation\NVSMI;C:\Users\user\AppData\Local\Microsoft\WindowsApps;C:\Cloud SDK\google-cloud-sdk\bin;C:\altera\13.0\modelsim_ase\win32aloem;C:\Program Files\Microsoft VS Code\bin;C:\Users\user\AppData\Local\Programs\MiKTeX 2.9\miktex\bin\x64\;C:\Users\user\AppData\Local\Continuum\anaconda3\envs\venv\lib\site-packages\numpy\.libs

and paste it in a new variable in run/debug configuration and in python console as:

But that didn't solve the problem. Please note that I tried installing scipy using conda install scipy , and the problem wasn't solved. Finally, the problem doesn't arise while working from cmd, but do exist when working from python console (inside pycharm) and pycharm.

I found out that running print(os.environ['PATH']) within the python console inside pycharm gave me the following:

Therefore, the following 2 paths are missing:

C:/Users/user/AppData/Local/Continuum/anaconda3/envs/venv;C:/Users/user/AppData/Local/Continuum/anaconda3/envs/venv/Scripts;

I have no idea how to fix this given all the attempts mentioned above

Any help is much appreciated!!

Answer 1

It seems you have misplaced the name of the environment variable and its value in the configuration dialog.

It should be PATH=list_of_paths , not list_of_paths=PATH
