after "17. right-click on INSTALL and build it" successfully, I still can't import cv2
I use window 10 x64 , python 3.6.2, Microsoft Visual Studio community 2017, cmake 3.10.0
I want to Building OpenCV from source with extra modules. So I follow the tutorial from https://docs.opencv.org/master/d5/de5.... after " Cmake" and generating .sln, I open the .sln with Microsoft Visual Studio community 2017. I built "ALL_BUILD" and "INSTALL" successfully, but still can't import the cv2 .
>>> import cv2
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: DLL load failed: 找不到指定的模块。
Actually, I used command conda list
in DOS, and there wasn't opencv.
the Cmake output are as follow:

i removed your useless screenshots. please edit your question again, and add text versions of whatever you think is nessecary. most importantly - we need to see the cmake output, too !
python cv2.cp36-win_amd64.pyd
-- that's the wrong command, it is not a python script. instead startpython
without anything else, and thenimport cv2
you seem to have 2 pythons on your machine, and it is taking the libs from
C:/Program Files/Python36/libs/python36.lib
but anything else fromD:/software/Anaconda3/install_path/envs/cntk-py36
. that's bad.most likely, it will install it here:
D:/software/Anaconda3/install_path/envs/cntk-py36/Lib/site-packages
, so make sure, you're calling the correct python.exe (also from there !)thank you. I have 2 pythons, they both are python 3.6.2 and controled by anconda.
I tried it again and payed more attention to what you said. Something interesting is that I add
D:/software/Anaconda3/install_path/envs/cntk-py36/libs/python36.lib
toPYTHON3_LIBRARY
, but after clicking on configure button, what I got is stillPython 3: Interpreter: D:/software/Anaconda3/install_path/envs/cntk-py36/python.exe (ver 3.6.2) Libraries: **C:/Program Files/Python36/libs/python36.lib (ver 3.6.2)** numpy: D:/software/Anaconda3/install_path/envs/cntk-py36/Lib/site-packages/numpy/core/include (ver ) packages path: D:/software/Anaconda3/install_path/envs/cntk-py36/Lib/site-packages
. what should I do?I rewrited the
CMakeCache.txt
. Now the second problem you listed are overcomed butimport cv2
still doesn't work.ImportError: DLL load failed: 找不到指定的模块。
After right clickinngALL_BUILD
and build it, I right clickINSTALL
and build it. They both are finished without error. However, what I got areD:/software/Anaconda3/install_path/envs/cntk-py36/Lib/site-packages/cv2.cp36-win_amd64.pyd
. what should I do next? someone told me there are severial setting process before right clickingALL_BUILD
. Is that true?
