I'm working on a project that requires python and some libraries. Almost everything works but there is one library that I can't get installed. It's about OpenKinect. You can find more information about it here: https://openkinect.org/wiki/Main_Page. I am running ubuntu desktop with python 3 installed.
i tried to install it using the instructions on the website but when i try to run it i get the error ModuleNotFoundError: No module named 'freenect'.
I want to make this project and improve it: https://www.instructables.com/How-You-Can-Make-a-Fully-Autonomous-Self-Driving-V/
All files are here: https://github.com/sieuwe1/Advanced-Real-Time-Self-Driving.
I've also tried to follow this guide: https://naman5.wordpress.com/2014/06/24/experimenting-with-kinect-using-opencv-python-and-open-kinect-libfreenect/ but when I try to install the necessary dependencies (step 2) I get this error:
Pakketlijsten worden ingelezen... Klaar
Boom van vereisten wordt opgebouwd... Klaar
De statusinformatie wordt gelezen... Klaar
Let op, 'git' wordt geselecteerd in plaats van 'git-core'
E: Kan pakket lubusb-1.0-0-dev niet vinden
E: Kon geen enkel pakket vinden via expansie (glob) 'lubusb-1.0-0-dev'
E: Kon geen enkel pakket vinden via regex 'lubusb-1.0-0-dev'
I leave it in Dutch to avoid mistakes.
When I type "cmake -L .." I get the following error:

I am trying to run cmake in our school project, the CMakeList.txt looks as follows:

When I run cmake .. in my build directory I get this output which looks almost OK:

Except the line -- Could NOT find PythonLibs (missing: PYTHON_INCLUDE_DIRS) (Required is at least version "3") which seems odd to me as few lines before it literally finds it:-- Found PythonLibs: /usr/local/opt/python#3.8/Frameworks/Python.framework/Versions/3.8/lib/libpython3.8.dylib. I tried to set an env variable PYTHON_INCLUDE_DIRS="/usr/local/opt/python#3.8/Frameworks/Python.framework/Versions/3.8/lib/libpython3.8.dylib" which is the exact same path as from the line above. Still, I get this error.
How can I make it find the PythonLibs? I really don't understand why the env variable doesn't work. I will also be happy to provide more info - I just don't know what.
I am using:
CLT: 12.0.0.0.1.1599194153
Xcode: 12.0.1
macOS Catalina ver. 10.15.7
Clang: 12.0 build 1200
PS: When I try to run make afterwards I get fatal error: 'string' file not found #include <string> which is maybe somehow connected to this issue...
It looks like I got the flags' names wrong. Calling the cmake with the following flags solved the problem for me:
cmake -DPYTHON_LIBRARY=$(python3-config --prefix)/lib/libpython3.8.dylib -DPYTHON_INCLUDE_DIR=$(python3-config --prefix)/include/python3.8 ..
It finds the PythonLibs successfully now.
❓ Problem with building PyTorch from source
Hello everyone,
I have problem with building PyTorch from source. I followed the official build instructions. I use Anaconda Python 3.7.1 (version 2018.12, build py37_0). I installed all neccessary dependencies using conda and issued python setup.py install command to build it. It builds all files successfully but then it fails at the installation step saying:
build/temp.linux-x86_64-3.7/torch/csrc/stub.o: file not recognized: file format not recognized
I tried building with gcc/g++ versions 5,6,7 but it did not help. Can you help me resolve this problem?

CMake Warning:
Manually-specified variables were not used by the project:

Problem solved.
I found what was wrong and I fixed it. The whole problem lies in the fact that Anaconda distribution comes with its own ld linker that is located in /opt/anaconda/compiler_compat/ and it overshadows system ld residing at /usr/bin.
To fix my error I ran python setup.py clean and then I temporarily renamed Anaconda's ld linker to ld-old to make it invisible during PyTorch installation.
I downloaded opencv and opencv contrib files, following the tutorial here: http://www.pyimagesearch.com/2015/06/22/install-opencv-3-0-and-python-2-7-on-ubuntu/
I want to install OpenCV3 for Python2.7 in a Conda environment called obj_recog. My OS is Ubuntu 16.04.
I then tried running the Cmake with different options, finally settling on this:
cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local \
-D WITH_TBB=ON -D BUILD_NEW_PYTHON_SUPPORT=ON -D WITH_V4L=ON \
-D WITH_QT=ON -D WITH_GTK=ON -D WITH_OPENGL=ON -D WITH_CUDA=ON \
-D CUDA_TOOLKIT_ROOT_DIR=/usr/local/cuda-8.0 -D WITH_FFMPEG=ON \
-D OPENCV_EXTRA_MODULES_PATH=~/opencv_contrib-3.1.0/modules \
-D PYTHON_EXECUTABLE=~/anaconda3/envs/obj_recog/bin/python \
-D INSTALL_PYTHON_EXAMPLES=ON -D INSTALL_C_EXAMPLES=OFF \
-D BUILD_EXAMPLES=ON -D WITH_CUBLAS=ON ..
Here is the output I get:
cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local -D WITH_TBB=ON -D BUILD_NEW_PYTHON_SUPPORT=ON -D WITH_V4L=ON -D WITH_QT=ON -D WITH_GTK=ON -D WITH_OPENGL=ON -D WITH_CUDA=ON -D CUDA_TOOLKIT_ROOT_DIR=/usr/local/cuda-8.0 -D WITH_FFMPEG=ON -D OPENCV_EXTRA_MODULES_PATH=~/opencv_contrib-3.1.0/modules -D PYTHON_EXECUTABLE=~/anaconda3/envs/obj_recog/bin/python -D INSTALL_PYTHON_EXAMPLES=ON -D INSTALL_C_EXAMPLES=OFF -D BUILD_EXAMPLES=ON -D WITH_CUBLAS=ON ..

When I execute make j-4 as in the tutorial, the make then breaks around 40%.
I also tried installing by using conda install opencv, but then I can't read .avi videos or images, getting the following error:
OpenCV Error: Unspecified error (The function is not implemented. Rebuild the library with Windows, GTK+ 2.x or Carbon support. If you are on Ubuntu or Debian, install libgtk2.0-dev and pkg-config, then re-run cmake or configure script) in cvShowImage, file /root/mc-x64-2.7/conda-bld/opencv-3_1482256854890/work/opencv-3.1.0/modules/highgui/src/window.cpp, line 545

Rebuild the library with Windows, GTK+ 2.x or Carbon support. If you are on Ubuntu or Debian, install libgtk2.0-dev and pkg-config, then re-run cmake or configure script in function cvShowImage
I checked and libgtk2-0-dev is correctly installed.
Before building OpenCV by hand, I also compiled and reinstalled ffmpeg and gstreamer.
During the make, I get this error:
//usr/lib/x86_64-linux-gnu/libsoxr.so.0: undefined reference to `GOMP_parallel#GOMP_4.0'
collect2: error: ld returned 1 exit status

Any help would be greatly appreciated !

If you follow this link and you can try running this code
git clone https://github.com/shantnu/Webcam-Face-Detect.git
cd cd Webcam-Face-Detect/
sudo python webcam_cv3.py haarcascade_frontalface_default.xml
typing the sudo python did the trick for me , i was getting errors when using just python.So try running with sudo.
This error is nothing to do with libgtk2.0-dev and pkg-config. Probably both are installed, but you still get the same error everytime you try to run make.
This often happen when you have tried to install opencv from different sources (for exemple opencv-python, official python, etc). Try to uninstall all opencv related packages (specially if they were not the official one), and start over. I even had to re-install ubuntu once.
The instructions from pyimagesearch work well.
Trying to install a Spenvis package and here's the error I'm getting when running the script:
-- Boost version: 1.41.0
-- Found the following Boost libraries:
-- python
-- Configuring done
-- Generating done
-- Build files have been written to: Desktop/build
make[2]: *** No rule to make target `/usr/local/lib64/libpython2.6.so.1.0', needed by `source/libSpenvis.so'. Stop.
make[1]: *** [source/CMakeFiles/Spenvis.dir/all] Error 2
make: *** [all] Error 2
It's looking for libpython2.6.so.1.0 in /usr/local/lib64, but the library itself is in /usr/lib64.
I'm not a super user, so I can't change/copy the library into the directory nor can I make a link to it. For reference, here's the python script I'm running followed by the CMakeLists.txt file:
"""
Main launch script
"""
import os
import sys
import shutil
from subprocess import call
"""
Define path where to find python packages
"""
loc_dir=os.getcwd()
os.chdir("python_utilities")
#Spenvis csv
#############
os.chdir("spenvis_csv")
if not os.path.exists("build"):
os.mkdir("build")
os.chdir("build")
call("cmake ../", shell=True)
call("make")
os.chdir(loc_dir)
os.chdir("python_utilities")
if not os.path.exists("lib"):
os.mkdir("lib")
for file_name in os.listdir("spenvis_csv/build/source"):
if file_name.find("libSpenvis.") !=-1:
shutil.move("spenvis_csv/build/source/%s" %(file_name),"lib/Spenvis.so")
os.chdir("..")
And the CMakeLists.txt:
cmake_minimum_required(VERSION 2.8)
# Make sure the compiler can find include files
include_directories (${PYSPENVIS_SOURCE_DIR})
# get boost
set(Boost_USE_STATIC_LIBS OFF)

add_library(Spenvis SHARED pySpenvisCSV.cc SpenvisCSV.cc SpenvisCSVCollection.cc)

Taking advice, I ran the following command in the directory with CMakeLists.txt file:
cmake -DPYTHON_LIBRARY='/usr/lib64/libpython2.6.so.1.0'
This churned out:
Boost found.
Found Boost components:
python

Going back to run the install.py program now returns:

-- Found the following Boost libraries:
-- python
-- Found PythonLibs: /usr/local/lib64/libpython2.6.so.1.0 (found version "2.6.6")

make[2]: *** No rule to make target `/usr/local/lib64/libpython2.6.so.1.0', needed by `source/libSpenvis.so'. Stop.
So, the same error is returned, only now it is claiming it's finding python libraries. Strangely, though, the python libraries it is finding don't exist, which is to say, there is no libpython2.6.so.1.0 in /usr/local/lib64 but instead it is located in /usr/lib64.
In the CMakeCache.txt, the lines concerning the desired library are as followed:
//No help, variable specified on the command line.
PYTHON_LIBRARIES:UNINITIALIZED=/usr/lib64/libpython2.6.so.1.0
//Path to a library.
PYTHON_LIBRARY:FILEPATH=/usr/lib64/libpython2.6.so
//Dependencies for the target

The /usr need to be insert in front of CMAKE_PREFIX_PATH, so it will be found first.
