Thanks for replying. Here's my version info

  • Compiler: gcc 8.3.1
  • OS: CentOS Linux 8
  • python: 3.10.9
  • LightGBM: 4.0.0 (commit 32a5dbe)
  • Commands build the project
git clone --recursive https://github.com/microsoft/LightGBM  
cd LightGBM  
mkdir build
cd build
cmake -DOpenCL_LIBRARY=/usr/local/cuda/targets/x86_64-linux/lib/libOpenCL.so -DOpenCL_INCLUDE_DIR=/usr/local/cuda/targets/x86_64-linux/include -DBoost_LIBRARY=/opt/3rd/boost/lib -DBoost_INCLUDE_DIR=/opt/3rd/boost/include -DUSE_GPU=1 -DUSE_TIMETAG=ON .. && make -j
cp lib_lightgbm.so python-package/lightgbm/lib/

In addition, I used std::cout instead of the original code and I found this works for me:

 for (auto it = ordered.begin(); it != ordered.end(); ++it) { 
   // Log::Info("%s costs:\t %f", it->first.c_str(), it->second * 1e-3); 
   std::cout << it->first << " cost " << it->second / std::chrono::milliseconds(1) << std::endl;
 }
