Instalacja OpenCV w anaconda3 - Python.h: Nie ma takiego pliku lub katalogu

Question

Próbuję zbudować OpenCV 3.1.0 dla mojej instalacji anaconda3 i mój build zawodzi w:

[ 94%] Building CXX object modules/python3/CMakeFiles/opencv_python3.dir/__/src2/cv2.cpp.o 
/home/mikel/Soft/opencv/modules/python/src2/cv2.cpp:6:20: fatal error: Python.h: No such file or directory 
compilation terminated. 

mam OpenCV i OpenCV -contrib sklonowano w wersjach 3.1.0 przy użyciu git checkout 3.1.0 w obu i próbuję zbudować w ~/Soft/opencv/build gdzie mam opencv-contrib w ~/Soft/opencv-contrib. Używam Ubuntu GNOME 15.10 z i7-4960X.

Moim głównym celem jest, aby prace OpenCV w instalacji anaconda3 a więc moje polecenie cmake jest następujący:

cmake \ 
-D CMAKE_BUILD_TYPE=RELEASE \ 
-D CMAKE_INSTALL_PREFIX=/usr/local \ 
-D INSTALL_C_EXAMPLES=OFF \ 
-D INSTALL_PYTHON_EXAMPLES=ON \ 
-D OPENCV_EXTRA_MODULES_PATH=~/Soft/opencv_contrib/modules \ 
-D PYTHON3_EXECUTABLE=/home/mikel/anaconda3/bin/python3.5 \ 
-D PYTHON3_INCLUDE_DIR=/home/mikel/anaconda3/include/ \ 
-D PYTHON3_LIBRARY=/home/mikel/anaconda3/lib/libpython3.5m.so \ 
-D PYTHON3_PACKAGES_PATH=/home/mikel/anaconda3/lib/python3.5/site-packages/ \ 
-D PYTHON3_NUMPY_INCLUDE_DIRS=/home/mikel/anaconda3/lib/python3.5/site-packages/numpy/core/include \ 
-D PYTHON_DEFAULT_AVAILABLE=/home/mikel/anaconda3/bin/python3.5 \ 
-D BUILD_EXAMPLES=ON .. 

Wyjście mój rozkaz cmake jest tutaj: http://pastebin.com/qtd1wyMb - Wszystko w porządku, jak daleko, jak mogę widzieć.

I następnie uruchomić make -j12 zainstalować OpenCV i po kilku ostrzeżeniach to działa dobrze aż 94%, gdzie pojawia się następujący komunikat:

Wygląda na to, że mój problem polega na tym, że używam ścieżek anaconda3 zamiast standardowych ścieżek python3, nie można już znaleźć Python.h. Jednak, gdy instaluję przy użyciu instalacji python3, nie mogę zaimportować opencv do anacondy tam, gdzie jej potrzebuję.

Mam zainstalowane python3-dev i python-dev, więc Python.h powinien znajdować się na moim komputerze. Co muszę zmienić, aby openCV znalazł Python.h?

EDIT: stwierdziliśmy, że Anaconda3 za Python.h jest w anaconda3/include/python3.5m/tak ustawić PYTHON3_INCLUDE_DIR=anaconda3/include/python3.5m/ i teraz otrzymuję inny błąd:

Answer 1

Naprawiłem problem. Problem polegał na tym, że PYTHON3_INCLUDE_DIR został ustawiony na ~/anaconda3/include, podczas gdy Anakonda Python.h znajduje się wewnątrz ~/anaconda3/include/python3.5m. Ustawianie PYTHON3_INCLUDE_DIR=anaconda3/include/python3.5m/ poprawki ten problem, ponieważ teraz widzi Python.h

jednak doprowadziło to do innego problemu gdzie niektóre .h pliki takie jak hdf5.h i H5public.h nie były widoczne dla OpenCV jak były w głównej anaconda3/include/katalog , nie w podfolderze.

Rozwiązaniem tego było skopiować wszystkie pliki .h z katalogu include/ do katalogu include/python3.5m(kopiowanie zawartości zarówno do innego katalogu i ustawienie, które jako ścieżka będzie również działać) tak, że wszystkie. Pliki h znajdują się w tym samym folderze, który jest widoczny dla kompilatora. OpenCV teraz buduje!
