ImportError: DLL load failed: %1 is not a valid Win32 application. But the DLL's are there
I have a situation very much like the one at ImportError: DLL load failed: %1 is not a valid Win32 application, but the answer there isn't working for me.
My Python code says:
But that line throws the error shown in the title of this question.
I have OpenCV installed in
C:\lib\opencv on this 64-bit machine. I'm using 64-bit Python.
My PYTHONPATH variable:
PYTHONPATH=C:\lib\opencv\build\python\2.7. This folder contains
cv2.pyd and that's all.
My PATH variable:
Path=%OPENCV_DIR%\bin;... This folder contains 39 DLL files such as
OPENCV_DIR has this value:
The solution at ImportError: DLL load failed: %1 is not a valid Win32 application says to add "the new opencv binaries path (
C:\opencv\build\bin\Release) to the Windows PATH environment variable". But as shown above, I already have the OpenCV binaries folder (
C:\lib\opencv\build\x64\vc11\bin) in my PATH. And my OpenCV installation doesn't have any Release folders (except for an empty one under build/java).
Any ideas as to what's going wrong? Can I tell Python to verbosely trace the loading process? Exactly what DLL's is it looking for?
I just noticed that, according to http://www.dependencywalker.com/, the
C:\lib\opencv\build\python\2.7 is 32-bit, whereas the machine and the Python I'm running are 64-bit. Could that be the problem? And if so, where can I find a 64-bit version of cv2.pyd?
you can find any python libs from here
