使用R语言训练XGBoost模型时,为提高效率,打算运用GPU加速。我使用的是Win10系统,习惯用R语言,但这方面的中文教程比较少。我打算用这篇博文把摸索的过程和心得记录下来。 0 预备工作 这里参考了官方的教程:https://xgboost.readthedocs.io/en/latest/build.html#obtaining-the-source-code 首先要有支持CUDA 10.1及...
I have installed the newest multi-GPU xgboost from the source code(0.81.01) and the server has 8 GPUS. But when I change gpu_id to non-zero, there are some errors. Parameter n_gpus is ok. the test code: library('xgboost') # Simulate N x ...
但是今天有一个学员起初是下载R包无法联网，所以失败，根据我们的经验当然是options(download.file.method = 'libcurl')就轻轻松松解决啦，不过这次居然是仅仅是解决了R自带R包下载问题，使用BiocManager仍然是无法安装R包，如下所示：

GPU Accelerated XGBoost Decision tree learning and gradient boosting have until recently been the domain of multicore CPUs. Here we showcase a new plugin providing GPU acceleration for the XGBoost library. The plugin provides significant speedups over mu
