问题描述

在编译lightgbm GPU版本时并没有出错，但是在运行demo时发生了错误，错误如下：

解决方法

后来发现，源文件目录：src/treelearner/gpu_tree_learner.h的第26行代码：

#define BOOST_COMPUTE_USE_OFFLINE_CACHE

如果包含这个这个宏 BOOST_COMPUTE_USE_OFFLINE_CACHE，就会导致要寻找缓存目录，因此将其注释，并clean然后重新编译源文件，然后就能安装使用了。为了让大家能直接使用lightgbm，特将编译好的gpu版本的lightgbm上传。安装方法。

$ cd python-package$ python setup.py install
