我经常在Google Colabratory上运行LGBM,我刚发现此页面说LGBM默认设置为CPU,因此您需要先进行设置。https://medium.com/@am.sharma/lgbm-on-colab-with-gpu-c1c09e83f2af因此,我执行了页面上建议的代码或stackoverflow上建议的其他一些代码,如下所示,
!git clone --recursive https://github.com/Microsoft/LightGBM
%cd LightGBM
!mkdir build
%cd build
!cmake ../../LightGBM
!make -j4
!git clone --recursive https://github.com/Microsoft/LightGBM.git
%cd LightGBM/python-package
!python3 setup.py install --gpu
!pip install cmake
但是我仍然遇到错误
GPU Tree Learner was not enabled in this build.Please recompile with CMake option -DUSE_GPU=1
我该如何解决?谢谢!
运行后
! git clone --recursive https://github.com/Microsoft/LightGBM
您可以运行此oneliner,它将在colab中启用GPU的情况下构建和编译LightGBM:
! cd LightGBM && rm -rf build && mkdir build && cd build && cmake -DUSE_GPU=1 ../../LightGBM && make -j4 && cd ../python-package && python3 setup.py install --gpu;
