Library not found
ARUNSOORAJPS opened this issue · comments
'libSubsense' is not found inside the python folder. Should I do anything to create the library file?
File "C:/Users/ics02517.AD001/Documents/Python Scripts/Object Tracking/subsense-master/Python/Subsense.py", line 28, in init
self.lib_subsense = np.ctypeslib.load_library(LIB_NAME, LIB_PATH)
File "C:\Anaconda\lib\site-packages\numpy\ctypeslib.py", line 128, in load_library
raise OSError("no file with expected extension")
OSError: no file with expected extension
I have a same problem here... What should I do? I tried to cmake in the subsense root directory but libSunsesce doesn't created.
So... There is someone has solved this problem ?
I had a lot of problems too... Finally It compiled in this way:
1. Add the find_package command in My CmakeList.txt
basically I only added a find_package instruction, you can delete some lines there if you want.
SET(PROJECT_NAME Subsense)
PROJECT(${PROJECT_NAME})
CMAKE_MINIMUM_REQUIRED (VERSION 2.8.3)
find_package( OpenCV REQUIRED )
set(EXTRA_INC_DIRS
/usr/local/include
)
LIST(APPEND LINK_LIBS
opencv_core
opencv_video
opencv_features2d
opencv_imgproc
)
set(SS_DIR ${CMAKE_CURRENT_SOURCE_DIR})
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11 -Ofast")
if(APPLE)
set(CMAKE_INSTALL_RPATH_USE_LINK_PATH TRUE)
set(CMAKE_INSTALL_NAME_DIR ${CMAKE_INSTALL_PREFIX}/lib)
set(CMAKE_MACOSX_RPATH ON)
set(CMAKE_SKIP_BUILD_RPATH FALSE)
set(CMAKE_BUILD_WITH_INSTALL_RPATH FALSE)
set(CMAKE_INSTALL_RPATH "${CMAKE_INSTALL_PREFIX}/lib")
set(CMAKE_INSTALL_RPATH_USE_LINK_PATH TRUE)
endif()
file(GLOB LIB_SRC_FILES ${SS_DIR}/Subsense/*.cpp)
include_directories(${SS_DIR} ${EXTRA_INC_DIRS})
add_library(Subsense SHARED ${LIB_SRC_FILES})
target_link_libraries(Subsense ${LINK_LIBS})
2. Comment the lines 39-41 in the BackgroundSubtractorLBSP.cpp file as follows:
//cv::AlgorithmInfo* BackgroundSubtractorLBSP::info() const { //return nullptr; //}
3. Comment the line 29 in BackgroundSubtractorLBSP.h file:
//virtual cv::AlgorithmInfo* info() const;
**4. Locate the compiled libSubsense.so file together with the python script.
That's all.
@marcoruizrueda No brow... Getting the error even after trying out the above solutin

Do not forget to locate the libSubsense.so file in the same folder as the python script. I tried on Ubuntu 16.04 and CMake 2.8. Good luck.
@marcoruizrueda where is the file called libSubsense.so file, i can find it. And you want out to put that file inside the Python folder
And i am using Ubuntu 18.04 and Cmake 3.10. It will great full if you help me
libSubsense.so
From compilation with cmake, you are going to get the compiled file (libSubsense.so) that you have to put together with the python script. Please follow my 4 instructions faithfully and comment the results.
@marcoruizrueda Sorry i can't locate the libSubsense.so file in my system... So what should i do now?

So, set the file path in variable "LIB_PAT" in the python script, with the location of your compiled libSubsense.so file. It can be a remote location. So, that is the core problem, the file is not being found.
@marcoruizrueda I searched completely there is no file called libSubsense.so . Should i compile something to generate that file. And the variable name is LIB_PATH right?
@marcoruizrueda The fault was i dint make the Cmakelist.txt . After that process its working super fine. Thank you

Your welcome brow. Good luck.
The system could not find the specified file: Subsense. dll.
What should I do in this case?
