I am trying to run Lightgbm with gpu on Spyder. For installing the library I tried many commands but most have failed.
I tried "pip install lightgbm --install-option=--gpu" in anaconda prompt and got the
error.
The I followed the https://github.com/Microsoft/LightGBM/blob/master/docs/Installation-Guide.rst#build-gpu-version
I installed git, vs 2022, cmake and opencl(Cuda Toolkit)
For boost binaries I copied the boost_1_78_0 file in "C:\Boost".
But the file doesn't contain any "lib64-msvc-14.0"(or similar folder). This is the first problem but it contain libs folder so I gave that path(Hope that's right).
But then I get this error:
CMake Warning:
No source or binary directory provided. Both will be assumed to be the
same as the current working directory, but note that this warning will
become a fatal error in future CMake releases.
"CMake Error: The source directory "C:/Users/User Name/LightGBM/build" does not appear to contain CMakeLists.txt"
Any help is appreciated. Thanks

I am trying to build this code:
https://docs.opencv.org/3.2.0/d5/d6f/tutorial_feature_flann_matcher.html
I am using Ubuntu 16.04 with CLion 2017.3 and have OpenCV 3.4 installed.
xfeatures2d.hpp can't be found on the system.
I have looked at many different problems on the internet, but couldn't find a solution.
Any help?
You have to include cmake comiplation flag to opencv OPENCV_EXTRA_MODULES_PATH and set it to the opencv_contrib/modules.
cmake -DOPENCV_EXTRA_MODULES_PATH=../opencv_contrib/modules
Here's what I had to do to compile OpenCV with xfeatures2d:
Download opencv_contrib (I took a release from the releases page). This step is what gives us xfeatures2d.
Unpack the tarball somewhere, e.g., ~/src/opencv_contrib-4.5.5
When configuring OpenCV (the main OpenCV source like opencv-4.5.2) with CMake, add the following option to cmake command line (adjusting the value to be your actual path to the modules subdirectory of the opencv_contrib tarball):
-DOPENCV_EXTRA_MODULES_PATH=$HOME/src/opencv_contrib-4.5.5/modules/
Now just build as you normally would and install.
The above actions gave me the expected file (among others): /usr/include/opencv4/opencv2/xfeatures2d.hpp.
I'm trying to install Torch/Lua version and am getting the build errors shown below. I see this discussion on Github encountering the same errors, but I don't see a resolution to it.

What version of CUDA does torch require? My best guess right now is that this is a CUDA version mismatch.

It appears that these issues were related to the g++ version I had (4.8). I installed the latest g++ version (5.2), then had to delete the torch directory, re-clone it, and the installation worked. Note that build artifacts will be left over so actually removing the whole torch directory was necessary.
I am trying to install clang from source following the instructions as given in http://clang.llvm.org/get_started.html ( Steps 1-4 and 7) in Ubuntu 14.04
Inside the build directory , I ran make which succeeded. I wasn't sure what to do after that , so I ran make install inside the build directory, following which I got this cmake error:
There is no executable named clang in /build/bin folder anyway, but I can find others like clang-check, clang-query, etc. What's going wrong?
PS: My main requirment is to experiment with alpha security checkers of clang analyzer and also write my own checker later.
I am trying to install libqi for nao-ros and it gives me error: I already have gtest package but gtest_main is missing.
CMake Error at /home/shruti/d-prefix/share/cmake/qibuild/internal/uselib.cmake:80 (find_package): By not providing "FindGTEST_MAIN.cmake" in CMAKE_MODULE_PATH this project has asked CMake to find a package configuration file provided by "GTEST_MAIN", but CMake did not find one.
Could not find a package configuration file provided by "GTEST_MAIN" with any of the following names:
GTEST_MAINConfig.cmake
gtest_main-config.cmake
Add the installation prefix of "GTEST_MAIN" to CMAKE_PREFIX_PATH or set "GTEST_MAIN_DIR" to a directory containing one of the above files. If "GTEST_MAIN" provides a separate development package or SDK, be sure it has been installed.
Any one knows about it?
I had the same problem when trying to build libqi and fixed it by:
cd /usr/share/cmake-3.0/Modules
ln -s FindGTest.cmake FindGTEST_MAIN.cmake
I am compiling a dependency for a project on Ubuntu 10.10, and instead of having it install to /usr/local by default, I am instead installing it to /tmp/stage/usr/local. How do I go about informing CMake of the location of this custom installed dependency when I call it to generate the build files for said project.
I am running CMake 2.8.1, and I have tried to set CMAKE_PREFIX_PATH on the cmake command line, like so
cmake -D CMAKE_PREFIX_PATH=/tmp/stage/usr/local
but this doesn't seem to make a difference - the project doesn't seem to detect the dependency.
Also, if it matters, the project in question is OpenCV 2.2, and the dependency in question is FFMPEG...
I figured out how to fix my problem, and trying to point CMake at the appropriate install location isn't the issue.
Apparently, CMake is unable to find the pkg-config files for FFMPEG (i.e. libavcodec.pc, libavdevice.pc, etc.) that tell it where the FFMPEG headers and libraries are located. In a typical install scenario, these files would be located at /usr/lib/pkgconfig. However because of the custom install location, they are instead located at /tmp/stage/usr/local/lib/pkgconfig.
So that CMake could find these files, I had to add the following environment variable:
export PKG_CONFIG_PATH=/tmp/stage/usr/local/lib/pkgconfig
After which point, OpenCV built against FFMPEG as expected.
