在Ubuntu中安装Torch时CMake错误

Question

我正在尝试在PC（Ubuntu）中安装Torch。我遵循Torch网站中描述的步骤。但是，当我跑步

$./install.sh

我得到了错误：

CMake Error: The following variables are used in this project, but they are set to NOTFOUND.
Please set them or make sure they are set and tested correctly in the CMake files:
CUDA_cublas_device_LIBRARY (ADVANCED)
    linked by target "THC" in directory /home/leonardo/torch/extra/cutorch/lib/THC

所以我尝试分析CMake日志，并且出现以下错误：

/home/leonardo/torch/extra/cutorch/build/CMakeFiles/CMakeTmp/src.c:5:20: error: ‘luaL_setfuncs’ undeclared (first use in this function); did you mean ‘lua_setfenv’?
   long i = sizeof(&luaL_setfuncs);
                    ^~~~~~~~~~~~~
                    lua_setfenv
/home/leonardo/torch/extra/cutorch/build/CMakeFiles/CMakeTmp/src.c:5:20: note: each undeclared identifier is reported only once for each function it appears in
CMakeFiles/cmTC_0eb19.dir/build.make:65: recipe for target 'CMakeFiles/cmTC_0eb19.dir/src.c.o' failed

为什么会出现此错误？而我该如何解决呢？

对不起，我的英语有点生锈，如果有人听不懂，请告诉我以另一种方式解释所有这一切。 感谢所有帮助我的人。

PS：我先安装了NVidia CUDA Toolkit，也许是因为它造成了Torch的“奇怪”。

Answer 1

cublas_device库在CUDA 9.2中已弃用，而在CUDA 10中已删除。看起来您的Torch版本是针对cuDNN构建的，预期可在CUDA 9.2或更早版本上使用。

您可以：

1. 使用可与CUDA 10 https://github.com/nagadomi/distro配合使用的Torch叉子
2. 降级到CUDA 9.2或更旧版本

您需要了解的另一方面是确保NVidia GPU驱动程序，cuDNN和CUDA版本都可以一起使用。请参阅https://docs.nvidia.com/deploy/cuda-compatibility/index.html。

git clone https://github.com/nagadomi/distro.git ~/torch --recursive
cd ~/torch
./install-deps
./clean.sh
./update.sh

Answer 3

似乎手电筒不支持CUDA10。降级到CUDA 9.1

将CMAKE升级到3.12对我有用。

安装指南：
